news-2698Wed, 02 Nov 2022 10:14:52 +0100Instrument Systems VCSEL analysis camera wins Photonics Award industry awards Instrument Systems a prize for VTC 4000 infrared camera for the 2D near-field analysis of VCSEL arrays. Instrument Systems presented its new VTC 4000 infrared camera at Photonics West at the beginning of 2022. This camera has now received the “Laser Focus World Innovators Award 2022” in silver from a jury of experts from the photonics industry. The VTC 4000 VCSEL analysis camera was specially developed for the ultrafast, precise 2D near-field analysis of narrowband emitters, e.g. VCSELs or lasers. It can be seen live at the Instrument Systems Booth B5.418 at electronica 2022 in Munich in November. “VCSELs are components with an intrinsic single longitudinal mode and normally exhibit complex polarization properties,” says Stephanie Grabher, Head of Key Accounting at Instrument Systems. “The light they emit is typically linearly polarized along one of two orthogonal directions. If there is a change in temperature or bias current, abrupt polarization switching can be observed. VCSELs thus emit in more than one polarization state, so that their polarization angle cannot be controlled. In order to exploit the full performance potential of VCSELs while guaranteeing safe operation, this polarization dependency should also be taken into account in the measurement of magnitudes and absolute power.”
Thanks to an innovative one-shot process, the VTC 4000 simultaneously measures the spatial polarization of the single emitters of a VCSEL array in the near-field and supplies the information necessary to reduce the polarization dependency of the measurement setup. This procedure minimizes the error budget of the VCSEL test system and delivers highly accurate readings, e.g. for the eye safety of the laser source. In addition to defects, the infrared camera also characterizes position, power and radiation information of single emitters. In combination with a CAS spectroradiometer, the single emitter wavelengths can also be determined. An extended system with transmission screen measures the radiation behavior of emitters in the far-field.
In its portfolio, Instrument Systems has tailor-made solutions suitable for the characterization and quality control of the electrooptic properties of VCSELs in the lab and in production environments. The high-resolution array spectroradiometers of the CAS series are the central components of the VCSEL measuring systems. They offer a spectral solution up to 0.12 nm, and due to short integration times they are also suitable for high throughput rates in production. The PVT Pulsed VCSEL Tester is specially tailored to the time-resolved measurement of nanosecond pulses in the lab.

news-2591Wed, 18 May 2022 12:17:14 +0200Optical microsystems from Fraunhofer IPMS enable high-resolution fast light control microsystems are forging the Path of Light: The photonic systems of the Fraunhofer Institute for Photonic Microsystems IPMS can modulate light using small deflectable mirrors to create images and structures in a unique way. Hereby the research institute is developing spatial light modulators with up to several million mirrors on a semiconductor chip. The main areas of application for mirror matrices are in the fields of microlithography in the deep ultraviolet range, production of printed circuit boards (PCBs), semiconductor inspection and metrology, as well as in adaptive optics, astronomy, holography and microscopy. With its developments in this field, Fraunhofer IPMS is currently a world leader.

he latest development of Fraunhofer IPMS is a CMOS-integrated micro mirror array with two tilting axes per mirror and associated technology platform.

In addition to its use in the semiconductor industry, the innovation enables novel methods of imaging in microscopy, especially for biomedical applications. The latter are realized in cooperation with the “Fraunhofer center for Microelectronic and Optical Systems for Biomedicine" MEOS within the Fraunhofer IPMS.

At the 25th world's leading trade fair for photonics components, systems and applications - LASER - World of PHOTONICS - in Munich from April 26 to 29, visitors can find out about the latest developments at Fraunhofer IPMS. "One of our exhibits is the 2-axis tilting mirror demonstrator, which can be applied in optical beam steering, among other applications. In general, the micro mirrors of the IPMS spatial light modulators are individually tilted or deflected vertically, depending on the application, so that optical patterns are projected and thereby for example surface structures are formed," explains Dr. Michael Wagner, head of the Spatial Light Modulators (SLM) business unit at Fraunhofer IPMS. "Using the tilting mirror macromodels, visitors can also move the micro mirrors of the spatial light modulators themselves using a large model and gain an impression of the deflection functionalities that are possible," continues Dr. Wagner.



news-2601Sun, 15 May 2022 19:02:00 +0200Es werde Licht:Let there be a light: Lifecycle assessments for greener and more sustainable lamp designs fewer resources, avoiding electronic waste, and saving energy: This is possible if the entire production chain for more sustainable lamps is investigated and levelled up. For the SUMATRA project, researchers at Fraunhofer IZM and their industry partners are working together on exactly this mission. The precise eco lifecycle assessments and resulting design recommendations produced by Fraunhofer IZM and the environmental services provider Interseroh will assist lighting brands like TRILUX or OSRAM in making their production processes better for our environment and selecting more sustainable materials for their products.It is the ambitious goal of the European Green Deal to bring carbon emissions to a net zero and decouple economic growth from its dependence on resources – more than enough reason for companies to think again about sustainability. The eco lifecycle assessments of the SUMATRA project will contribute to this endeavour by putting in place the framework that is needed to produce lamps that are not only built to last, but easy on our natural resources and energy-efficient. For this purpose, the project team has set its sights on two key aspects of sustainability – the consumption of energy and materials – in the production of LEDs as well as entire lamps.

For the SUMATRA project, Fraunhofer IZM is taking a step back from lamp manufacturing on the ground for a bird’s eye view of the entire production chain. The eco-design experts of the Berlin-based institute are scrutinizing established lamp designs with targeted lifecycle assessments to find opportunities to improve the lamps’ environmental footprint in terms of resource efficiency and carbon emissions. What is unique about these assessments is their modular format that allows different types of LEDs, drivers or even lamp body designs and materials to be cross-compared with each other. The researchers at Fraunhofer IZM are sent designs and finished products from TRILUX, the lighting company and leader of the project, to conduct their assessments and come up with ideas about how to make the lamps more durable and more efficient. One aspect that is of particular interest for TRILUX is the question of repairability, with lamps designed from the outset with later repairs and maintenance in mind. OSRAM, another leading lighting brand involved in the project, works on optimizing the system architecture to make sure that LED drivers can be more easily replaced, repaired, or reused in new configurations. At the other end of the chain, Interseroh is bringing its perspective to the table: The recycling experts care about the end-of-life stage and want to know what needs to change in lamp designs to facilitate recycling and help circular economy concepts along.

The project researchers have come to focus on three specific steps in the process. The first is a solid and comprehensive dataset to help ecological lifecycle assessments for LED lights, as the available data is frequently outdated. The second key factor addresses the question of resource efficiency writ large, going beyond the usual emphasis on a lamp’s energy efficiency. This can mean scaling the circuit board just right to make the best use of the available space with the best possible light yield. A balance needs to be found between the efficient use of the materials and the performance of the lamp in real-life working conditions. As modern LED lights are already far more efficient than their conventional forebears, saving resources in this respect is an important step towards more sustainable production processes. The third and final focus of the project addresses the ability to tear down a lamp at the end of its life: Easy disassembly is a precondition for correct recycling. On these and other factors like the choice of materials, the SUMATRA assessments will offer important pointers towards effective improvements.

Product developers in the industry can use these insights to feed into their new designs and receive regular feedback about their environmental footprint from the specialists at Fraunhofer IZM. Good communication between research and industry plays a major role for the success of the project. This also includes the careful balance between economic realities and eco-design potential: Lamp designs must be economical in their use of materials, but also energy-efficient, and price-sensitive. In industrial and office lighting in particular, there is little room to accommodate even smaller price increases for a more sustainable design. The immense leap in efficiency that came with the switch from conventional lightbulbs to LED lighting will not be replicated when updating an older LED lamp with newer units, even though the ecological benefits are still evident. Lamps should be both: Good for our environment, but also easy on the price tag.

TRILUX intends to take forward the findings from SUMATRA into several new lamp designs after the conclusion of the project, and it hopes to benefit from the work with Fraunhofer IZM in the form of insights with lasting relevance for later projects. The job for Fraunhofer IZM is to find the general eco-design principles that will continue to benefit future lamp designs. And in the long run, all of this will feed through to the end user with lamps to enjoy for longer and with a cleaner environmental conscience.

The SUMATRA project is supported by the Federal Ministry of Education and Research as part of the research campaign “Resource efficiency for the energy transition”. The €1.1 million project is scheduled to run from 1 June 2021 to 30 September 2023.



news-2564Wed, 13 Apr 2022 11:38:41 +0200Miniature external cavity laser (Mini-ECL) with 200 kHz linewidth and SM Laser Diode with 400 mW fiber output @ 808nm - both in standard butterfly package eagleyard continues its ambitious innovation path with the launch of two highly innovative laser diodes – counting launch #3 and #4 in 2022 At this year’s LASER World of PHOTONICS taking place in Munich, Germany from April 26th -29th TOPTICA eagleyard will introduce the Mini-ECL @ 780 nm and the SM Laser Diode with 400 mW fiber output @ 808 nm – both in standard butterfly platform. These two new products are part of the innovation path of the company as they are launched just shortly after the highly appreciated µMOPA and the tapered amplifier in standard butterfly package. Both products were presented in January 2022 with the µMOPA even being nominated as SPIE Prism award finalist.
All four new products unite the high integration - comprising many features in a robust butterfly package that brings along various advantages.

The Mini-ECL is a single frequency laser diode with a super fine linewidth of typical 100 kHz. A stable performance is ensured by the integrated cavity in the hermetically sealed butterfly package. Moreover, wavelengths between 650 – 1100 nm are customizable upon request, opening more freedom across the spectrum. The standard product at 780 nm will mainly be used for spectroscopy (Rb D2 line), metrology and atomic clocks.

Product Highlights:
•    80 mW @ 780 nm
•    Small linewidth of typ. 100 kHz
•    Very good SMSR (typ. 50 dB)
•    Integrated beam collimation
•    Thermal management by integrated thermoelectric cooler and thermistor

The advantages of the Mini-ECL become very obvious when looking at the reduced complexity based on the integration of the cavity. Due to the ease of use, the robustness of the package and therefore scalability, not only research applications will benefit from this innovation but commercial and industry requirements are more easily fulfilled than with already available solutions. This will lead to outstanding results and applications along the value chain.  
The new 400 mW SM Laser Diode benefits from all mentioned advantages of the hermetically sealed butterfly packages as well. With its introduction, TOPTICA eagleyard highlights again its thrive for innovation as this unique product is the first single mode laser diode with a 400 mW output power from fiber at a wavelengths of 808 nm on the market. It is focused on power delivery with a center wavelength around the absorption peak 808 nm (a tighter tolerance can be achieved with FBG upon request). A brilliant polarization is achievable for higher efficiency.

The 400 mW SM Laser Diode will mainly be used as pump for fiber lasers, for optical tweezers and in optical communication.

Product Highlights:
•    400 mW single mode output ex-fiber @ 808 nm
•    CW operation
•    PM fiber output, plug and play with fiber pigtail
•    Thermal management by integrated thermoelectric cooler and thermistor

Four new products being launched within four months are not the only news from TOPTICA eagleyard: The company will present a new, modern logo at the LASER World of PHOTONICS along with several surprises at their booth #B5.331. 


news-2544Wed, 09 Mar 2022 14:42:27 +0100Silicon carbide pressure sensors working at 600°C could make air travel easier on the environment to take the heat: While conventional sensors reach breaking point at around 300°C, researchers at Fraunhofer IZM are creating a sensor that works reliably at twice that temperature. The secret of the heat-loving sensors: Silicon carbide, etched with exceptional precision. Their ability to monitor pressure even in extremely adverse environments could help fine-tune the combustion process in jet turbines and reduce the fuel consumption of aircraft.Humans have dreamt of flying since our species first looked up to the sky. From the story of doomed Icarus to the design genius of Leonardo da Vinci, myth and imagination were slowly enriched with scientific and technical knowhow. Latest since the arrival of jet engines in the mid-20th century, humanity has  taken to the skies in ever larger and ever more powerful flying machines. The working principle of the jet engine seems simple on the surface: An extremely powerful exhaust jet from the gas turbine engine generates thrust that propels the aircraft forward. But the picture becomes more complex when one looks under the hood. The compression of the air inside the engine creates enormous pressure, and the combustion chamber reaches temperatures of up to 600° centigrade, or more in the even more extreme conditions of rocket engines. To guarantee safety and be able to monitor these conditions in use, sensors need  to fulfil tough requirements: They not only have to be sensitive and precise enough, but also absolutely reliable and durable in extremely adverse and corrosive environments.

In the north of Germany’s capital Berlin, researchers at Fraunhofer IZM have taken on the mission to design and build a high-temperature sensor with the right properties. Silicon carbide or SiC, their material of choice, represents a quantum leap for the robustness of pressure sensors. Conventional silicon sensors  would not be an option for this type of application, as they would reach their limit already at 150°C. With the Silicon-on-Insulator (SoI) technology, this limit can be pushed to around 400°C. But when this threshold is crossed and the sensors are exposed to mechanical pressure, they begin to deform and  immediately lose precision.

Using SiC for the new generation of high-temperature sensors comes with many evident advantages: The material is extremely robust, chemically virtually inert, and stable even at high temperatures. It can cope with a vast temperature range, reaching up to 600°C. Its mechanical and chemical properties led to it being recognized as a possible gamechanger for microelectronics years ago. But the positive properties come at a price: “Silicon carbide is a blessing and a curse. The unique strength and durability of the material make it very promising for electronic components, but the same properties make processing SiC a real headache”, Piotr Mackowiak, researcher at Fraunhofer IZM, knows.

The team gathered around Mackowiak has now found a solution to this conundrum. The challenge for them was to create a semiconductor manufacturing process to build a tiny, but stable base body on a thin membrane. They did so with an extremely fast double etching process that etches the silicon carbide at  four micrometres per minute. This is eight times the conventional speed, and it makes the technology interesting for the high throughput rates in industrial production. The sensor created by Mackowiak’s team also has an unusual shape that keeps the design stable at high temperatures without any need for  external cooling.

“Our thinking was to keep the design to the essential basics, to ensure that it is heat resistant, but also so thin that it can bend and work as a piezometer – and we did both with deep etching”, Mackowiak explains. Current sensors in this field work by piezoelectric measurements, which can record dynamic, but not  static pressure, and they cannot withstand the very high temperatures they are exposed to for too long. “Our sensors use the piezoresistive effect, which means that they can track both dynamic and static pressure, and that over long periods at even higher temperatures.” The sensor and the package are now  available to future project partners, who could also get involved in adapting the sensors for other environmental parameters.

Sensors that work reliably at high temperatures of up to 600°C could make air travel easier on the environment. By monitoring the thermo-acoustic pressure oscillations and other process  parameters right in the jet turbine, the system allows far better control over the process: The fuel-to-air ratio could be fine-tuned for more efficient and cleaner combustion. In the end, this would reduce the amount of jet fuel needed to fly. Small changes to the design can alter what the sensors measure, which  would make the new sensors an interesting choice not just for air travel and spaceflight, but potentially also for electric cars or deep drilling.


news-2538Tue, 01 Mar 2022 12:32:33 +0100Research in the deep freeze: Fraunhofer IZM develops integration techniques for cryo-electronics technology and ultrafast computers using superconductors are no longer a vision for the far-off future, but some of the hottest topics in current electronics research. One major challenge remains: The electronic structures used to connect and work with the quantum parts of the quantum computers, such as qubits on chips, are often far bigger than the qubits themselves. Researchers at Fraunhofer IZM have innovated a process that could fit twice as many connectors on the same surface than conventional technology thought possible. Their idea of using indium bumps will now be used to optimize the control electronics in the quantum computers and devices of the future. A dedicated cryometrics lab was set up in Berlin to test the performance and potential of their designs.It is a common trope in science fiction: The novel’s or film’s protagonist is put into stasis in a cryochamber, only to wake up hale and sound even though centuries have passed in the meantime. As far-fetched as this might seem, the idea is grounded in real-life science: Cryotechnology. It works by turning gasses into liquids at temperatures of below -160°C. Long a reserve of experimental research since the principles of cryotechnology were developed in the late 19th century, the technology has recently attracted the attention of many people in industry for the great practical potential of working at such extreme temperatures: In spaceflight, cryosensors are used for gravitational measures or for low-noise amplifiers for extremely weak signals in the vastness of space. Cryosurgery can help treat damaged tissue. But one field where cryotechnology really comes into its own is: Quantum technology. The quantum world holds much promise in many practical fields, from computing or sensor technology to quantum  communication. But this promise will only come true once working and, above all, genuinely scalable production technologies are available. For a quantum computer to run calculations and accelerate actual applications, it needs additional qubits that it can work with – hundreds of thousands or even millions of tiny physical bodies. These qubits  are connected with each other via superconducting circuits, which have hardly any measurable electrical resistance once they are cooled down past a certain threshold. But reading and manipulating qubits needs an electronic switch with sufficient port density, and it needs to be thermally decoupled to stop its own heat signal from  destroying the quantum entanglement of the qubits. What theorists call quantum supremacy – the point at which quantum computers outperform the most powerful conventional computers – can only be achieved with high numbers of qubits. Researchers expect this number to range in the six or seven figures, but the actual number of qubits  that could be placed on a semiconductor chip is generally limited by the port density. Current technology has been stuck at a pitch, i.e. the distance between individual contacts, of 15 micrometres for several years, but now the research team of Dr Hermann Oppermann of the Fraunhofer Institute for Reliability and Microintegration IZM has  achieved the seemingly impossible: With galvanic deposition of indium, they created a pitch of less than 7.5 micrometres.

As the system needs to be kept at a temperature of 20 milli-Kelvin during operation, its electrical connections can only give off minute amounts of thermal energy. This is what superconducting materials were created for. Hermann Oppermann and his fellow researchers managed to deposit and structure superconducting niobium and niobium  alloys, the materials used for contacting vias through several layers of substrates, in socalled interposers. The end product of their work is an extremely low-loss circuit carrier that can connect entire qubit arrays in real time and integrate them into highly dense, but scalable systems for quantum computing.

Fraunhofer IZM set up a dedicated  cryometric lab in Berlin as the place where this fundamental technology could be developed, suitable materials tested, integration concepts optimized, and superconducting interconnect technologies trialled for cryogenic applications. The new lab facilities let the researchers test, characterize, and evaluate electrical circuits and make progress  with integration technologies for extremely low temperature scenarios. Individual circuit components are cooled down to an unimaginable 3 Kelvin to analyse their resistance properties and draw conclusions about their electrical performance and the reliability of the vias, redistribution layers, and control systems at cryo-temperatures.

Projects are  under way to explore new packaging and interconnection technologies for integration under cryogenic conditions, and first measurements have already produced results. “As one of our next steps, we will be moving this cryogenic packaging and interconnection technology in the direction of high-frequency, millimetre-wave technology.” Hermann  Oppermann has reasons to be optimistic: “We are constantly learning more in this field, which is creating amazing potential in the market for possible applications. This is not limited to quantum technology, but also opens up new prospects for conventional applications, like high-performance computing or cryosensors. We are always interested in  other projects that could benefit from our expertise with packaging technologies for cryogenic applications.”


news-2512Fri, 28 Jan 2022 11:26:24 +0100New ITU focus group boosts digitization of agriculture worldwide International Telecommunications Union (ITU) has created a new focus group to explore the digitization of agriculture. The new focus group "AI and IoT for Digital Agriculture" (FG-AI4A) aims to work closely with the Food and Agricultural Organization of the United Nations (FAO) using new digital technologies to make the global agriculture sector fit for the future. Dr.-Ing. Sebastian Bosse, group leader of the "Interactive & Cognitive Systems" group in the "Vision and Imaging Technologies" department at Fraunhofer Heinrich Hertz Institute (HHI) will chair the focus group. By 2050, nearly 10 billion people will live on this planet, according to calculations by the United Nations. To ensure an equitable and secure food supply despite this population increase, we need to transform agricultural practices and technologies across the globe. To this end, the ITU, together with the FAO, has established the new focus group “FG-AI4A” to explore the use of Artificial Intelligence (AI) and the Internet of Things (IoT) in agriculture in order to identify standardization gaps and scalability opportunities. The global initiative is creating a platform that provides open access to digital innovations for all stakeholders in the agricultural sector from science, industry and practitioners.

For this purpose, the focus group will examine the potential of novel technologies for agriculture in a variety of use cases. These include, for example, data acquisition and processing, agricultural data modeling, and AI-based decision support to optimize agricultural processes. AI, IoT, connected services, and autonomous systems enable agricultural stakeholders to tailor decisions, such as fertilizer application or medical examinations, to individual crops or to individual animals. This precision enables more effective interventions, making agriculture more sustainable by helping to produce more using fewer resources.

"Our focus group is tackling the major challenges facing agriculture in the future with a solution-oriented, intelligent and, above all, global approach. Global networking is essential in the search for use cases, best practices and relevant standardization gaps. In addition to its technical expertise, Fraunhofer HHI will support this project through specific experience in digitized agriculture. A good example of this is our BMWi-funded project NaLamKI. In NaLamKI, we are working with partners from industry and science to examine the use of AI for sustainable crop farming. Together, we are developing intelligent methods along the entire agricultural process chain," says Chairman Dr.-Ing. Sebastian Bosse. The focus group will put special emphasis on applications in developing countries, where people's livelihoods depend heavily on agriculture. In fact, these are also the countries where digital solutions will have the greatest impact in making agriculture more sustainable and resilient.

Practical implementation of the focus group's work will support the achievement of the United Nations Sustainable Development Goals. The potential of AI and IoT in agriculture can contribute to reducing poverty and hunger. At the same time, it will promote dignified work, economic growth, infrastructure, sustainable consumption and climate protection.

To prepare for the first group meeting in March 2022, the focus group will recruit experts who can provide valuable perspectives to future focus group meetings through ITU "AI4Good" seminars, hosted by the chairs, in the coming weeks.


news-2494Thu, 20 Jan 2022 10:45:09 +0100Let There Be Light! startup Crocus Labs is revolutionizing agriculture with new LED technology for indoor and vertical farming. Interview: Olaf Bryan Wielk, ideenmanufaktur

Whether you grow lettuce, peppers or cannabis, you need light. Dependency on sunlight and the seasons has been one of the main constraints of agriculture and horticulture for thousands of years. But one Berlin startup aims to change that.

Today we are interviewing Dr. Prashanth Makaram, founder of Crocus Labs, who with the support of HTGF, seed investor for innovative technologies and business, aim to revolutionize farming.

So Prash, congratulations on your successful financing round. What does Crocus Labs do?

We bring sunlight into indoor spaces in order to enable the farming of a wide variety of crops while utilizing as little resources as possible.

Did you discover an interest in gardening as a child, or why are you intent on changing how we grow stuff?

No, it was more that as an adult I became interested in the impact of agriculture on biodiversity. On trips to Costa Rica and to Madagascar I noticed the beauty and fragility of undisturbed nature. I started to look for ways to protect what is left of it. So much of today’s form of agriculture has a harmful impact on rainforests through deforestation and consequent biodiversity losses. So I wanted to do something in that area, and since I come from a technology background I wanted to do something with a technical angle to it.

So the question I was asking myself was, how can we change today’s agriculture practices? At that time I began to look at indoor farming, which as a market was starting to catch up. And I saw that maybe this could be a solution, if we can make it widely adoptable. So with Crocus Labs we basically try to enable vertical farms so that they can provide an alternative to today’s farms and in that way we can stop biodiversity losses. That is my main drive behind it all.

What are “vertical farms”?

Well, in a generic way you can say indoor farms can be either greenhouses or vertical farms. Vertical farms are what we call “controlled environment agriculture”. So you basically grow everything in a very controlled manner inside a building. The crops are stacked on top of each other. This means that the resources you are using, from land, water, to pesticides etc., are much lower. So you can grow a lot more in a smaller area and produce food where most people live, inside cities, to keep transportation short.

And your solution to make these vertical farms more efficient has to do with light. So how is your artificial light better than sunlight?

Well actually, we try to remake the sunlight indoors. So the problem with sunlight is on the one hand that we don’t get enough of it in big parts of Europe. In the Netherlands growers already use artificial lights in greenhouses. Vertical farms rely even heavier on artificial lights, because the plants are stacked. In vertical farms you cannot bring the light uniformly to all the plants all the way down the stack. If you have five or ten storeys of plants that you’re growing, sunlight usually hits only the top two and by the time you get to the bottom you don’t have any light. Actually most vertical farms do not even have glass ceilings.

So basically our idea is to recreate the sunlight using proprietary lighting technologies so that you get the same amount of light across all the plants but without creating a huge burden on electricity consumption.

One of the biggest problems at the moment for vertical farms is that although the idea is nice, they may grow a handful of crops but they also have a huge carbon footprint, because of how much electricity is being consumed. We want to reduce this footprint so that vertical farms can become more meaningful and competitive with other agriculture.

Taste is also a big challenge because the lighting solutions currently available are too far away from the sun’s spectrum.

How far are you on the way to achieving all that?

We had a pre-seed round last year and now we just closed a big round with the High-tech Gründerfonds. We have two major customers who are ready to pilot with us. One of them is a big strawberry producer in northern Germany, the other is a big Berlin company. So this year we will grow the team, and yeah, we’re actively recruiting at the moment!
Fruits growing on indoor plants taste just as good when provided with light that recreates sunlight’s natural spectrum.

Now, you’re already claiming that your solution will be a lot more cost-effective than the competition. How so?

We talk about costs in terms of the whole thing, capital expenses plus operational expenses. So if for the same price we can give you lights that are much more efficient than the competition’s, then over the course of four or five years your total expenses are a lot less. So you get a lot more light output on the amount of Euros you spend, which means that your production costs are much lower. This is particularly interesting as you start growing higher value crops like berries.

So what is the core difference in the technology?

The core difference in technology is that we are the only company at the moment building lights from the ground up for this specific use case. We build our own LE diodes and our smart lighting systems make use of not only our proprietary LED technologies, but also sensor systems and advanced algorithms. And this goes back to our semiconductor know-how. We have been able to get a lot of light output with very little current.

This is one part of it. The second part is that we have been able to recreate the effects of real sunlight, which is crucial for taste. So these are the major advantages that we bring.

So there are surely more use cases for this new technology, right?

Yeah, there are. I think one of the biggest topics coming up is what is called “human-centric lighting”. In houses and office spaces they want to bring light that acts more like sunlight. If you look at many of today’s lights they mostly have a big blue peak, which means that is not very good for your sleep. So if you have white light on at night and then you try to go to sleep it affects your circadian rhythms. So human-centric lighting and lighting that matches the circadian rhythm is about getting people to sleep better and have better work schedules.

Your experience is in semiconductors. How much new stuff did you have to learn in the last couple of years?

A lot! Because this is the first time I am carrying my technical knowledge to farming. I don’t have anybody in the family with a farming background. So I had to learn a lot about indoor farming.

And lighting is not a space I was in before. I was in a lot of consumer sensors and medical devices, so lighting and how indoor lighting affects plants is something I had to learn over time. And also the whole complexity of light in the context of greenhouses and vertical farms. Not to mention how the lighting industry works.

Why did you choose Berlin as a base for Crocus Labs?

Berlin is my favorite European city. I did my PhD in the United States in Boston. I first came to Europe in Spain for my first startup, through which I had my initial introduction to Berlin because it was incorporated with Bayer pharmaceuticals. So I was here working with Bayer. And then I just fell in love with Berlin. It’s very cosmopolitan, it has a lot of energy, in terms of people it is a very human-centric city. It has this drive, creative as well as entrepreneurial.

My wife and I spent two years in Munich, but we very much prefer Berlin and desperately wanted to come back here. The one part is the human aspect, the second part is that there are very nice networks in Berlin, the universities and also the entrepreneurial startup networks. Berlin is a very welcoming city.

Where did the name Crocus Labs come from?

Back then we wanted to grow saffron, because saffron is a high-value crop, and crocus is basically the flower that gives you saffron. So that’s how we started Crocus Labs. We don’t do anything in saffron at the moment, so maybe we’ll re-brand at some point. Or we’ll keep it. It’s a nice name!

So this is, what, your third startup now?


So third time lucky?

I hope so!

2022 is going to be an exciting year for you. We wish you the best of luck!

Berlin, as one of Europe’s most exciting metropoli, may seem far removed from the countryside but could well be where the next revolution in farming technology originates.

news-2446Tue, 09 Nov 2021 21:24:25 +0100Turning quantum discoveries into real-life products with advanced R&D facilities in Berlin computing is hailed everywhere as the technology of the future, but what about quantum sensing and communicating? These capabilities promise to make quantum technologies the seed for a new generation of products in information and communication technology and modern sensor systems. But manufacturers who want to use the great potential and fundamental principles of quantum mechanics need highly specialized facilities and processes. With funding from the EU and the State of Berlin, researchers at Fraunhofer IZM have created a vision of a technology centre to power the development of new glass-based quantum technologies.Quantum objects measure just a handful of nanometres in scale, but they exhibit some unique behaviour: They do not exist in a certainly knowable position, nor do they move in a definable direction. Quantum particles can be entangled, even when they are far removed from each other. It is these phenomena that have inspired researchers worldwide to develop new quantum technologies with immense potential for applications in a wide range of industries.

The Fraunhofer Society is already playing its part in shaping this revolution with Germany’s first quantum computer, installed at the start of the year. But quantum research is not only about computing, as photonic quantum technologies promise groundbreaking innovations in quantum communications and sensors. In order for these revolutionary inventions to make their way into scalable components and market-ready products, researchers have to find ways to measure quantum states reliably and precisely.

Berlin’s QuantumPackagingLab will open in mid-2022 and is expected to become the go-to place for developing reliable packaging solutions for quantum photonics with its exceptional technical facilities. Researchers at the lab will be pursuing ambitious plans in their quest to close the remaining technology gaps and bring the second quantum revolution into industrial applications. Their endeavours include using glass as a transparent substrate and carrier for photonic circuits or expanding established waveguide technologies into the visible and near-infrared range, the so-called VIS-NIR spectrum. The researchers are using panel-level integration approaches originally designed for electronic circuit boards. To prepare the existing packaging and system integration technologies for this leap into quantum photonics, the Fraunhofer Institute for Reliability and Microintegration IZM is creating a completely new infrastructure landscape in no fewer than four separate labs, with five units playing a particularly crucial role:

Scanning Nearfield Optical Microscope (SNOM)

  • How it works:

As the centrepiece of the optical measurement lab, the SNOM uses optical spectroscopy to scan the surfaces of nanophotonic components. To do so, it focuses an incredibly narrow laser beam, with a smaller diameter than a waveguide, in the immediate proximity of the sample. Highly reliable measurements are also possible by using the evanescent field that is created around a surface when a light wave fades.   

  • What it brings:

The SNOM gives researchers the ability to characterize nano-photonic components with extreme precision, at a resolution far below the diffraction limit for distortion-free imaging. The plans include the eponymous scanning near-field optical microscope for exploring the evanescent field of glass-embedded waveguides and optical nanofibers to optimize the interaction between light and matter as well as fluorescence microscopes for nanostructures (e.g. individual molecules, nitrogen-vacancy defects in diamonds, quantum dots, or nanocarbons).

Waveguide coupler

  • How it works:

This large automated unit uses an integrated camera and search and optimization algorithms to couple several waveguides with a fibre array. The coupled light can then be detected at the waveguide’s output side.

  • What it brings:

For glass-embedded waveguides to become usable in quantum technology, their production process has to be adjusted for the visible and IR light spectrum, with single-mode light guiding and minimal propagation losses. This has already been possible with a custom system built at Fraunhofer IZM, but the researchers hope to make the measuring processes much faster and more precise with the new facilities.

3D Glass Printer

  • How it works:

The 3D glass printer uses ultrashort light impulses to model glass structures. Its surfaces can then be modified by etching. The printer unit is expected to be particularly useful for laser direct writing, that is, the use of a laser to create waveguides and other photonic structures like diffraction gratings directly in the glass. The system will also be able to drill microcavities or weld glass by heating up only the immediate target area to create transparent, but hermetically sealed glass-on-glass joints.

  • What it brings:

The 3D glass printer opens up a world of possibilities: Level or curved optical surfaces can be created directly on the waveguides e.g. to activate quantum emitters. The novel weld joints will be crucial for thermally insulating quantum sensors or for producing miniature spectroscopy cells. The researchers expect a tenfold improvement over conventional technology in the roughness, precision, and reproducibility of glass structures created with this system.

Micro Ultra-High Vacuum Bonder

  • How it works:

The new bonder will be used for laser soldering and other hermetic joining processes for glass in a vacuum. The highly focused laser beam is absorbed by the glass solder, heating it up to the melting temperature and creating a joint between two glass surfaces.

  • What it brings:

The micro ultra-high vacuum bonder will be particularly useful for testing new ways to join glass surfaces. The key is to create joints that are hermetically sealed on the microlevel to allow the development of micro vacuum or micro gas cells or other thermally insulated designs.

Ultra-High Vacuum Vapor Deposition Unit

Highly Precise Vacuum Metalizing

  • How it works:

In the ultra-high vacuum vapor deposition system, glass surfaces can be metallized with extremely fine coats of only a few nanometres, applied with a record precision of a single nanometre. This process is used to create semi-transparent metalized mirrors or to turn the metalized surfaces themselves into plasmonic guides.

  • What it brings:

The system is taking the capabilities of conventional sputtering to the quantum technology domain. It can be used to create parallel or confocal gold coats with microscopically tiny cavities along the waveguide. When quantum emitters enter these cavities, the emission patterns change, and light particles are far more likely to be emitted in the direction of the waveguide.

Fraunhofer IZM is looking for research partners to tread new ground in application-driven system integration, especially assembly and packaging technologies, for quantum communication and quantum sensors.

The QuantumPackagingLab is supported by the State of Berlin with EFRE co-funding at an amount of €3,392,000.

Das FBH besitzt langjährige Erfahrung bei der Entwicklung und Fertigung von robusten, kompakten Diodenlasermodulen für anspruchsvolle Weltraumanwendungen. Die Module haben ihre Leistungsfähigkeit bereits mehrfach in Experimenten unter Schwerelosigkeit bewiesen. Unter anderem fertigt das FBH derzeit 55 ultra-schmalbandige Lasermodule, die es für die BECCAL-Apparatur (Bose-Einstein Condensate – Cold Atom Laboratory) entwickelt hat. Sie sollen in der vom Deutschen Zentrum für Luft- und Raumfahrt DLR und der NASA ab 2024 betriebenen Forschungsanlage für quantenoptische Experimente mit ultra-kalten Atomen an Bord der internationalen Raumstation ISS eingesetzt werden. Fundamentalphysikalische Fragestellungen mit Quantenobjekten sollen damit nahe dem absoluten Temperaturnullpunkt (-273,15 °C) hochgenau untersucht werden.

Kernstücke dieser und bisheriger Diodenlasermodule sind am FBH entwickelte Laserdioden, die gemeinsam mit Optiken und weiteren passiven Elementen mit höchster Stabilität und Präzision aufgebaut werden. Dank der einzigartigen Mikrointegrationstechnologie des FBH sind die Module extrem robust und ideal für den Einsatz im Weltraum geeignet. Sie zeichnen sich durch geringe Abmessungen von nur 125 x 75 x 23 mm³, eine geringe Masse (750 g) sowie exzellente Leistungsparameter aus: Ausgangsleistungen > 500 mW bei zugleich schmaler intrinsischer Linienbreite < 1 kHz werden erreicht.

In enger Zusammenarbeit mit der Humboldt-Universität zu Berlin werden derartige Module auch zu kompakten Quantensensoren und optischen Uhren für den Einsatz im Weltraum und für industrietaugliche Systemlösungen in der Quantentechnologie aufgebaut. Das gemeinsame Joint Lab stellt eine neuartige, völlig autonome frequenzstabilisierte Laserquelle mit integrierter DFB-Laserdiode vor, die auf dem D2-Übergang in Rubidium bei 780 nm basiert.

Lasermodule für Satelliten: von Kommunikation bis Klimaschutz

Weitere Lasermodule entwickelt das FBH für Satellitenanwendungen. Laserdiodenbänke (LDB) des Instituts werden seit vielen Jahren erfolgreich als Pumplaser in Laserkommunikationsterminals (LCT) der Firma Tesat-Spacecom eingesetzt. Damit werden unter anderem hohe Datenmengen der Erdbeobachtung besonders schnell zwischen Satelliten und zur Erde übertragen. Die LDBs werden nach den Standards der Europäischen Weltraumorganisation (ESA) für Weltraumanwendungen entwickelt und qualifiziert. Deren Wellenlänge wird so auf das Pump-Übergangsband eines Nd:YAG-Lasers stabilisiert, dass der Laserstrahl des Pumplasers die stabile LCT-Leistung gewährleistet. Hinzu kommt die exzellente Zuverlässigkeit über die gesamte 15-jährige Lebensdauer der Mission.

Das FBH zeigt auch ein DBR-Laserarray-Modul, das dank eines auf Chipebene integrierten, die Wellenlänge stabilisierenden Bragg-Reflektors sowohl ein geringes Rauschen als auch eine hohe Zuverlässigkeit bietet. Die Eignung derartiger Module wurde für einen Dauerbetrieb von mehr als 15 Jahren nachgewiesen. Damit qualifizieren sie sich als Flughardware für die nächsten LCT-Weltraummissionen. Ein weiterer Pumplaser soll künftig auf dem Klimasatelliten MERLIN eingesetzt werden, der die Methankonzentration in der Atmosphäre messen soll. Dafür hat das FBH Lasermodule entwickelt, qualifiziert und geliefert, die jeweils mit zwei Hochleistungslaser-Halbbarren ausgestattet sind. Diese Module liefern 130 W gepulste Emission bei 808 nm und pumpen einen Nd:YAG-Laser. Die Leistungsfähigkeit und Zuverlässigkeit über die gesamte Missionsdauer wurde anhand umfangreicher Qualifikationen der Technologie nachgewiesen und vom ESA-Technologiezentrum ESTEC bestätigt. So degradiert die Leistung selbst bei einer langen Betriebsdauer von über vier Milliarden Pulsen nur unwesentlich.

Energieeffiziente Komponenten für Satellitenkommunikation und -sensorik

Wegen ihrer hohen Strahlungshärte und der möglichen hohen Schaltfrequenzen eignen sich Galliumnitrid (GaN)-Schalttransistoren besonders für das Power Conditioning in Satelliten. Der vom FBH neu entwickelte 10 A/400 V Aluminiumnitrid Power Core mit GaN-Leistungstransistoren in Halbbrücken-Konfiguration minimiert Streuinduktivitäten und Kapazitäten der Schaltzelle. Dabei werden Leistungsschalter, Gatetreiber und DC-Link-Kondensatoren extrem kompakt heterointegriert und die Wärme wird effizient durch das Aluminiumnitrid-Substrat abgeführt. So konnten die Schaltzeiten der Leistungszelle gegenüber einem traditionellen Aufbau mit diskreten Bauelementen halbiert werden. Hohe Schaltfrequenzen bei gleichzeitig hohem Konverter-Wirkungsgrad sind die Voraussetzung für Leistungskonverter mit besonders hoher Leistungsdichte. Ein zentraler Aspekt, da jedes Gramm im Weltraum zählt.

Stromverbrauch und Verlustleistung sind weitere kritische Punkte beim Betrieb von Leistungsverstärkern im Weltraum. Daher entwickelt das FBH Konzepte zum Envelope Tracking – eine bekannte Technik, um die Effizienz von Hochfrequenz-Leistungsverstärkern zu steigern.


news-2433Fri, 22 Oct 2021 10:54:47 +0200Meet Prima, PicoQuant’s new multiple color pulsed diode laser stand alone, compact laser module provides three individual wavelengths at an affordable priceIn a recent webinar, PicoQuant has unveiled its latest laser innovation: the stand alone, fully computer controlled laser module Prima.

“Our objective when developing Prima was to offer a solution to a common challenge faced by many researchers. They often need more than a single excitation wavelength to study all of their samples, but buying multiple lasers can become quite expensive. So we tapped our 25 years of expertise in laser development to create an affordable, compact module that can emit red, green, and blue light”, says Guillaume Delpont, Product Manager at PicoQuant.

Prima generates laser light at 635, 510, and 450 nm with each color being emitted individually, one at a time. These three wavelengths cover most of the excitation needs for daily lab tasks, such as lifetime or quantum yield measurements, photoluminescence, and fluorescence. The new laser module supports pulsed operation with repetition rates up to 200 MHz, continuous wave (CW) mode as well as fast switching CW capability with a rise/fall time of less than 3 ns. In pulsed mode, each wavelength can achieve an average optical output power of typically 5 mW, and up zo 50 mW in CW mode.

Thanks to its stand alone design, Prima does not require any additional laser driver. All settings and operating parameters are fully computer controlled via an intuitive, WindowsTM based control software. Prima’s flexibility and ease-of-use make it a versatile yet affordable tool for many research applications in life or materials science.


news-2427Fri, 15 Oct 2021 12:10:29 +0200Tiny package, greater depth – A plenoptic high-speed camera designed by Fraunhofer researchers at Fraunhofer IZM have joined forces with TecVenture, Optrontec Inc., and KAIST to create a high-speed camera fitted with a unique multi-lens array that can capture images with a far greater depth of field than its conventional counterparts. The miniaturized electronics make the system a good choice for efficient damage analytics in industrial use or for many research activities. To prepare the camera for reliable work in the tough reality of industrial environments without compromising its compact size, the electronics for the system were miniaturized by Fraunhofer IZM using the Institute’s embedding technology. As production processes are accelerating everywhere in industry, manufacturers need the right means to monitor these processes at every link in the chain. Increasingly, their weapon of choice for this mission is high-speed cameras. But conventional cameras struggle with adjusting their focus quickly enough to track objects moving through their field of vision. A solution is to use cameras with a greater depth of field with the same optics, with the focus virtually adjusted by processing the resulting image data to produce a clear image at the right depth. The Fraunhofer IZM researchers and their partners took on the challenge of creating a high-speed and highly miniaturized camera capable of this feat.

The right lens is chosen for the application and the image focused on a full-format sensor. A special multi-lens or polarization filter array, made by KAIST and Korea’s Optrontec, is placed in the path between lens and sensor to get a greater depth of field and better contrast to capture even the fine structural details of the monitored objects. Operating at a speed of 2000 images per second – a tenfold increase compared to conventional cameras – the system enables an accurate visual analysis of the very fast, often critical processes happening in laboratories or factories.

The Micro-Lens Array (MLA) consists of a closely populated matrix of lenses, each placed only 150 micrometres from the next. All of the components needed to supply the image sensor are mounted directly beneath the sensor itself in a highly integrated embedded module.

With 3D stacking and different electronic components embedded directly in the circuit board, the system could not only be miniaturized into a tiny package, but also equipped with far shorter electrical connections, a must-have for better signal quality in high-speed systems of this nature. The almost completely encapsulated design also makes the system extremely rugged and robust. The highly integrated electronic module was created with the production facilities available at Fraunhofer IZM.

The camera revealed its exceptional performance immediately in the first functional trials. Over the next months, the production process will be refined and ramped up for industrial use. But the plenoptic camera is not only a great tool for industrial process analysis: Its combination of great speed and an excellent depth of field also makes it a promising choice for scientists exploring other biological, chemical, or physical processes.

news-2390Mon, 13 Sep 2021 12:13:52 +0200TOPTICA: New powerful laser passes field test powerful experimental laser developed by the European Southern Observatory (ESO), TOPTICA Projects1 and other industry partners2 passed a key test last month at the Allgaeuer Volkssternwarte Ottobeuren observatory in Germany. The adaptive-optics laser has important additional capabilities compared to existing systems. It is to be installed at the European Space Agency’s (ESA) Optical Ground Station in Tenerife, Spain, in the frame of the ESO–ESA Research & Development collaboration. The higher laser power and its chirping system will lead to significant improvements in the sharpness of astronomical images taken with ground-based telescopes. The technology also opens the door for developments in laser satellite communication.Astronomical adaptive optics refers to systems on ground-based telescopes that correct for the blurring effect brought about by turbulence in the Earth’s atmosphere — the same effect that causes stars seen from Earth to “twinkle”. To remove the distortions, these systems require a bright reference star close to the object of study.
Because these stars are not always conveniently placed on the sky, astronomers use lasers to excite sodium atoms at 90 km altitude in the Earth's atmosphere, creating artificial stars near the field of interest that can be used to map and correct for the atmospheric turbulence.
The narrow band highest optical quality laser power of 63 Watts locked to the sodium wavelength as such is already a significant leap forward compared to current astronomy laser technology. However, a second important step has been the experimental frequency chirping system developed and implemented by TOPTICA Projects in collaboration with ESO, that is targeted to also improve the signal-to-noise of the adaptive optics system.
Chirping consists in rapidly changing the frequency to which the laser is tuned. This increases the number of sodium atoms excited by the laser, making the artificial star brighter and thus improving the turbulence correction. TOPTICA has installed the chirping prototype on the ESO 63 Watts CaNaPy laser and, together with ESO, has commissioned on sky both the laser and its novel chirping system.
Once the technology is installed at the ESA Optical Ground Station in Tenerife — a collaborative project between ESO and ESA — it will provide both organizations with opportunities to advance the use of laser guide star adaptive optics technologies not only for astronomy but also for satellite optical communication.

news-2379Mon, 06 Sep 2021 14:32:14 +0200New European Academy to boost the skills and know-how of industry in exploiting opportunities in the €615B global photonics sector programme to train thousands of industry workers in the adoption and development of innovative photonics-based solutions to some of society’s biggest challenges, from environmental sustainability to healthy living and smart infrastructure, has been established by a consortium of over 50 of Europe’s top photonics competence centres. The European Photonics Academy will offer training courses beyond the lecture room with a strong focus on hands-on training. Course attendees will gain real-world experience using state-of-the-art design, manufacturing, test equipment and facilities. The academy’s training centres will offer unique courses across a wide range of photonics technology platforms and application domains. The academy will initially run for four years with the clear intention of becoming a sustainable long-term support to European industry.

Interest in photonics is booming, with the global photonics market estimated to be worth €615B in 2020 and recent research showing that the European photonics market is growing at more than double the rate of global GDP. However, gaining access to the cutting-edge technical know-how and the hands-on skills required to utilise photonics technologies remains difficult for many companies, especially small- and medium-sized enterprises (SMEs). The academy, launched by PhotonHub Europe, the full-service one-stop-shop Photonics Innovation Hub funded by the European Commission, will make it easy for SMEs in particular to fully exploit this critical enabling technology for their own innovation activities.

“For the first time the European Photonics Academy means that SMEs have a one-stop-shop to pick and choose from a large menu of training options, making it easy to get the exact training course suited to their needs. Companies can be assured that their employees are getting top quality training from best-in-class facilities since quality assurance is overseen by PhotonHub,” said Prof Peter O’Brien of the UCC Tyndall Institute in Ireland, who leads training support services at the academy. “We expect to support 6,000 European companies with training over the next four years, each sending several employees on one or more of our courses, with several hundred companies immediately taking up photonics technologies in their applications and product manufacturing as early adopters. As a result, we believe the academy will be a massive catalyst for the take-up of photonics by European companies.”

Photonics involves the generation, manipulation and detection of light and is a key enabling digital technology that underpins many existing and emerging applications. Over the next decade photonics will make a significant impact to our everyday lives – transforming industries, tackling critical issues such as climate change, and improving societies across Europe. Some current applications include:

  • Agriculture (scanning technology and infrared imaging to monitor food production and quality, and sensor systems for planting and irrigation)
  • Green Energy Sources (LED lighting and Photovoltaic devices used for solar electric panels)
  • Information Communications Technology (optics for data storage, transmission across fibre-optic networks and displays)
  • Life Sciences (testing and analysis devices such as non-invasive glucose monitors and point-of-care and wearable diagnostics)
  • Medical Technology (lasers for surgery, photodynamic therapy, smart surgical instruments).

Europe is a global leader in the development of photonics technologies, with much of this innovation generated through research funded by the European Commission. The new academy will allow European workforces access to state-of-the-art photonics technologies and advanced methods of photonics manufacturing through structured training and education. To-date, 40 training centres across Europe have been selected for funding, with 10 more to be announced later this year. Critically all regions of Europe will have access to training, including those with little or no expertise in photonics, with centres as far apart as Ireland, Spain, Finland and Greece.

Three types of training courses are available:

  • Online Training, geared towards new entrants to the photonics sector providing a half-day introduction to photonics and an overview of the key enabling power of photonics technologies for wide-ranging applications.
  • Demo Centres, offering one-day training courses on-site with a focus on particular photonics technology applications.
  • Experience Centres, offering in-depth three-day or five-day training courses with a strong focus on lab-based activities and hands-on working using state-of-the-art equipment and application demonstrator tools.

People wishing to attend any of the Online Training, or either of the Demo or Experience Centre training courses, can browse the training catalogue via the PhotonHub website and register for the particular course of interest to them.

Further details about PhotonHub’s extensive Online Training, and Demo and Experience Centre training courses, can be found in the HERE.

news-2370Mon, 23 Aug 2021 09:53:00 +0200Astrophotonics – an emerging field in astrophysics by Dr Aline Dinkelaker and Dr Aashia Rahman in an international editorial team, two renowned journals in the area of optics and photonics have published a joint feature issue on the topic of astrophotonics, one of the research fields of innoFSPEC Potsdam at the Leibniz Institute for Astrophysics Potsdam (AIP).Astrophotonics deals with photonic components for astronomy, which are intended to become an integral part of the next-generation astronomical instruments. Initiated by AIP researchers, the journals JOSA B and Applied Optics of the Optical Society (OSA) dedicated a joint feature issue to this topic. This feature issue, for which Dr Aline Dinkelaker and Dr Aashia Rahman acted as guest editors and contributed an introduction to the subject, looks into some of the significant developments in astrophotonics and shows the scientific maturity of this research field.

Collectively, more than 20 papers in different areas of astrophotonics, and their applications in instruments for astronomy, are being published from research communities worldwide. Dr Kalaga Madhav, head of the research group Astrophotonics at AIP, summarises the publications: “The articles from research groups around the world cover a broad range of astrophotonic topics, such as interferometric beam combiners to create extremely sharp images, e.g. of stellar surfaces or the environment of black holes, miniaturized spectrographs “on-a-chip” for next generation space telescopes, high precision frequency combs for the detection of exoplanets, and many more. The activities of the Astrophotonics group at AIP are prominently reflected in as many as six publications, after all a quarter of the papers in the feature issue”.

The launch of this feature issue celebrates the ongoing progress in astrophotonics and its incorporation into instrument designs: Fibre-based spectroscopy, which started with novel designs at the onset of innoFSPEC, is now an established and trusted technology and is included in instruments such as the future telescope 4MOST. The same development is foreseen for astrophotonics at innoFSPEC, and the researchers are already establishing collaborations and testing their components at telescopes and in astronomical instruments. With reference to the future of astrophotonics, section head of innoFSPEC professor Martin Roth states enthusiastically, ”The emerging area of astrophotonics has already supported important discoveries in astronomy, e.g. the ground breaking work of Nobel laureate Reinhard Genzel about the black hole in the Galactic Center. Given the level of maturity and reliability that this technology has now reached, we expect that innoFSPEC, in collaboration with international partners such as the European Southern Observatory (ESO), will launch more exciting innovations”.

The excellence centers innoFSPEC in Germany and CUDOS in Australia were the first research groups to focus on exploring the diverse research areas under astrophotonics. However, the publication of this feature issue indicates that the emerging area of astrophotonics has now gathered momentum in many countries. The agreement for a joint astrophotonics research collaboration, signed between AIP and ESO in 2020, is another indication for the growing importance of the field. The editorial team of the feature issue consisted of nine members in total, with Professor Joss Bland-Hawthorn, an ARC Laureate Fellow Professor of Physics and Director of the Sydney Institute for Astronomy (SIFA) as the lead editor.

“As researchers in astrophotonics, we see how fast the field advances. With the feature issue, we wanted to provide a platform to showcase the progress and highlight this relatively young topic to scientists from other research fields. As experimental physicists, being guest editors for a journal was new to us. It was an exciting experience to be engaged in every level of the entire publication process, especially in the exchange with authors, journal staff, and the community. Accompanying the manuscript from submission through peer review, finally leading to a high-quality publication, is very rewarding”, say Aline Dinkelaker and Aashia Rahman, who since 2019 have been focusing on bringing the idea of this feature issue from conception to fruition.


news-2368Wed, 18 Aug 2021 15:54:00 +0200Panel Level Packaging Consortium 2.0 – The First Year! the COVID-19 crisis, Fraunhofer IZM and its 17 partners on the PLC 2.0 consortium have achieved excellent results within the first year. All partners met in a virtual meeting for two days. The time difference for such world-wide meetings is a challenge, therefore several sessions have taken place over the whole day to have easy access form Asia, Europe and the US.In 2016, Fraunhofer IZM teamed up with a group of industry leaders from Europe, the US, and Japan to develop the fundamental processes for new panel level packaging technologies that are ready to transition to industrial-scale high-volume production. The first incarnation of Panel Level Packaging Consortium (2016–2019) consisted of 17 international partners from industry and was judged to be a high-powered and impactful project, having a recognized expert for substrate technologies and wafer-level packaging at its helm in the form of the Fraunhofer Institute of Reliability and Microintegration. For its first run, the focus of the consortium was on the entire process chain in panel-level packaging: from assembly, molding, wiring, and cost modelling to standardization.

With the second consortium launched for 2020–2022, this focus has shifted to die placement and embedding technology for ultra-fine-line wiring down to 2 µm lines and space with a potential move to 1 µm. As such, migration effects and ways to exploit the migration limits of fine line wiring have become areas of interest for the consortium’s international members, including another 17 partners from industry: Ajinomoto Fine-Techno Co., Amkor Technology, ASM Pacific Technology Ltd., AT&S Austria Technologie & Systemtechnik AG, Atotech, BASF, Corning Research & Development Corporation, Dupont, Evatec AG, FUJIFILM Electronic Materials U.S.A., Intel Corporation, Meltex Inc., Nagase ChemteX Corporation, RENA Technologies GmbH, Schmoll Maschinen, Showa Denko Materials Co. Ltd (former Hitachi Chemical Company, Ltd), and Semsysco GmbH.

The PLC 2.0 project has again made excellent progress: New equipment for panel level packaging had been installed during the run-up to the PLC 2.0, and the project benefits from several major investments made by the German Federal Ministry of Education and Research to promote the Research Fab Microelectronics Germany. The impact of the global COVID-19 pandemic and the subsequent lockdown restricted access to laboratory work and to the research network of the Fraunhofer IZM, leading to the work plan for the PLC 2.0 being extended by 4 months. All meetings of the first year were organized in virtual format with two dedicated sessions for the relevant Asia and US time zones.

One major focus of the project has been the investigation of warpage and die shift in large format reconfigured panels (18” x 24”), and considerable progress has already been made towards understanding the root causes. With these insights, the relevant parameters can now be controlled better to enable large-area fine-line RDL processes. The analytical effort has paid off, as RDL could be scaled down considerably on the panel level, making the most of the advantages of both wafer and panel-level technologies and paving the way for an entirely new process chain with new equipment and materials.

Building on this achievement, the consortium’s partners are now expecting twelve months of agile progress with developing and managing viable process options on the road to a complete high-yield process chain. The test structures for electrochemical migration tests were also designed in accordance with the IPC standard; the design of the test vehicles was guided by the standard’s description of the IPC multi-purpose test board, but with the structure sizes matched to the geometries reflecting the goals of the PLC 2.0 project as interdigital structures. Researching a combination of economic and environmental assessments to promote more sustainable production approaches is another strong part of the PLC 2.0. A first model to estimate the carbon footprint of the PLP technology has already been established. This first calculation will help all members to identify the most energy intensive stages and further improve the data quality in the most relevant steps.

Tanja Braun, Group Leader at Fraunhofer IZM, is the public face of the Panel Level Consortium: “What makes me happy about our work is seeing such a diverse consortium coming together and making progress towards one shared goal: Finding future manufacturing technologies for maximum integration density on the panel level.”

Instrument Systems has been accredited for tests in the field of lighting technology to DIN EN ISO / IEC 17025 since 2009 and is now offering accredited testing of radiant flux and luminous flux with the “Goniospectroradiometry of optical radiation sources” procedure.This procedure has enabled the development of UVC-LED reference sources with traceable reference values of maximum precision for radiant flux and irradiance. These reference sources are used for monitoring and calibrating UV measuring equipment, e.g. the ISP-PTFE series.
The accreditation of test labs is extremely important for photometry customers. With it they receive the assurance that their measuring equipment delivers reliable and traceable results. At the same time, the accredited testing of the measuring instruments often used in production guarantees the high quality of the final products and instills a high level of confidence in the final customer. Instrument Systems therefore maintains a test lab accredited to DIN EN ISO / IEC 17025 that offers traceable tests of all relevant photometric and radiometric measurands from UV to the NIR range with numerous measuring procedures and is flexibly and securely positioned for the future.
The highly experienced lighting technology engineers at Instrument Systems developed a test procedure that is conformant with standard CIE 239:2020 and accredited for the production of high-precision UV-LED reference sources. The traceable reference values for radiant flux are determined by the measurement of UV-LED sources with a goniospectroradiometer consisting of a high-precision goniometer of the LGS series and a CAS spectrometer – likewise traceably tested by the test lab – with an irradiance optical probe. Extremely low extended measurement uncertainties (k=2) of reference values of only 4.5% (UVC), 3.5% (UVB) and 2% (UVA) can be achieved with this combination. Details of the procedure have been published in several trade magazines: LpS Digital Conference Proceedings 2021 (EN), ELEKTRONIKPRAXIS 11/2021 (DE), LEDs Magazine, September 2020 (EN).

news-2357Tue, 10 Aug 2021 15:07:00 +0200Initiative QuNET demonstrates highly secure and practical quantum communication, two German federal authorities communicated via video for the first time in a quantum-secure manner. The QuNET project, an initiative funded by the German Federal Ministry of Education and Research (BMBF) to develop highly secure communication systems, is thus demonstrating how data sovereignty can be guaranteed in the future. This technology will not only be important for governments and public authorities but also to protect everyday data.It was a foretaste of the communication of the future - or rather, the "data security" of the future. Because when Federal Research Minister Anja Karliczek invited members of the Federal Office for Information Security (BSI) to a video conference today, everything looked the same, at least for outsiders. Together with Andreas Könen, Head of Department CI "Cyber and IT Security" at the Federal Ministry of the Interior, Building and Community (BMI) and BSI Vice President Dr. Gerhard Schabhüser, the minister talked via video stream.

And yet this videoconference opens a new chapter in the highly secure communication of the future. Because what the eye can't see: The conversation was not encrypted using conventional methods but by means of light quanta. The trick is that if an attacker tries to access the to be generated keys, which are later used for data transmission, the light particles are manipulated. This manipulation is detected together by the sender and receiver, thus preventing an interception attempt. The detection is based on physical principles. If an eavesdropping attempt is discovered, the key is discarded and a new one is generated. By means of this strategy, only private keys are kept and therefore long-term security of the agreed keys is achieved. This sets a new milestone for data confidentiality in the digital world.

A new chapter for the highly secure communication of the future

This so-called "quantum communication" will become necessary in the light of future technological developments: In the future, quantum computers and new algorithms are expected to be able to crack previously used methods of data encryption. According to the motto "store now, decrypt later", data can already be stored today and read later, e.g., with the aid of more powerful computers.

This threatens especially data that requires long-term protection, i.e., data that will still be of great value to hackers in the distant future. This includes not only information from governments and authorities, but also corporate secrets or personal health data of citizens.

Federal Minister of Education and Research Anja Karliczek explained: "Quantum communication is one of the key technologies that play a crucial role in IT security and can help us prepare for future threats. This is so important because cyber security and cyber sovereignty are preconditions for the stability of democracy and also why I launched the QuNET initiative two years ago. QuNET is an important driver of the translation of findings from basic research on quantum communication into systems that are suited for everyday use. Our objective is to take advantage of the work of QuNET and the other projects on quantum communication funded by the Federal Research Ministry to lay the foundations for an ecosystem of producers and providers of quantum communication solutions in Germany. In this way, we can ensure the swift translation of innovative technologies and components into broad application. "

In order to be able to protect the privacy of citizens as well as states and companies in the future, there is already a great need for action today. It is not just a matter of developing new and highly secure communication systems based on quantum know-how but also of finding ways to integrate this new technology into existing IT infrastructures (e.g., fiber optic cables) and to take established cryptographic processes into account. There is also a particular challenge when it comes to long distances. Here, satellites can play a central role.

Long-term data security through encryption with quantum

The QuNET initiative pursues the goal of enabling long-term data security. On the way to achieving this goal, today researchers from all participating institutes realized the first quantum-based video conference between BMBF and BSI in Bonn, Germany. The focus of the QuNET work is the so-called "quantum key exchange", also known as QKD (short for "Quantum Key Distribution"). QKD enables the exchange of symmetric keys whose security can be quantified. The BSI is supporting the QuNET initiative and is preparing accompanying and independent test criteria in international cooperation.

At the end of last year, the research organizations involved in the initiative - the Fraunhofer-Gesellschaft, the Max Planck Society and the German Aerospace Center (DLR) - presented important basic principles for modern and secure communication standards. Accordingly, the scientists have further developed the overall architecture for systems for quantum-safe communication, as well as possibilities for exchanging quantum keys over long, medium and short distances using free-space and fiber systems.

In the setup of the first quantum-based videoconference between BMBF and BSI, multiple free-space and fiber quantum channels have been used. This corresponds to a more complex scenario than a connection via a single quantum channel. Besides the video conference aspect of the demonstration, the set-up was also used to produce scientific data which might give important insights for communication in complex quantum secure networks of the future.

Multiple devices from PicoQuant’s MultiHarp product line were connected using Low Jitter White Rabbit switches from Seven Solutions the leading manufacturer of White Rabbit components. The authors have investigated how various network topologies, optical fiber lengths, and presence of Ethernet traffic affects the time accuracy of connected MultiHarp 150 and MultiHarp 160 devices.

Download the free white paper from PicoQuant’s or Seven Solutions’ website to learn more about the flawless interoperability of the MultiHarp devices with the switches from Seven Solutions. The experiments described in the paper demonstrated that - when using White Rabbit - the excellent timing performance of the MultiHarp can be maintained for reasonably sized networks and a timing jitter of less than 45 ps rms can be expected for such cases. Furthermore, the authors showed that the impact of fiber length differences of up to 5 km or simultaneous Ethernet data transmission was negligible.

White Rabbit technology is an open source project aimed at realizing an Ethernet-based net-work permitting simultaneous sub-nanosecond synchronization over long distances. White Rabbit is a powerful technology that allows synchronizing large numbers of detection channels over long distances without having to sacrifice any of the aforementioned channels for this pur-pose, which makes it highly valuable for a range of emerging applications such as e.g., quan-tum communication.


news-2332Wed, 07 Jul 2021 14:26:00 +0200Dutch Royals Visit Photonics in Berlin July 7, the photonics community in Berlin enjoyed a public event with some rare guests: During their visit of the German Capitol Berlin, the Royal couple of the Netherlands visited a meeting of OpTecBB, the local photonics network, and PhotonicsNL. The latter is the national photonics network of the Netherlands. Both societies signed a memorandum of understanding at this occasion.The Berlin metropolitan region has a rich history in optics, photonics and quantum technology. Research and industry went hand in hand here, from eye glass development or the first electric light bulb to modern EUV lithography. Many of these developments were shared with Dutch organizations.
Two of the city’s leading institutions hosted the royal visit: Technische Universität Berlin, an institution with a major research focus on photonics and optical systems, and the Fraunhofer Heinrich Hertz Institute, an organization with an international reputation for research into quantum and non-quantum communication networks, artificial intelligence, and photonic integrated circuits.
During the royal visit, the ceremonial Atrium at Technische Universität Berlin was transformed into a showcase for light-based future technologies and German-Dutch cooperation. At the start of the program, competence networks Optec-Berlin-Brandenburg and PhotonicsNL officially celebrated their collaboration and signed a Memorandum of Understanding to increase this cooperation further and used the occasion to promote the global competitiveness of Europe as a center of Photonics innovation.
Professor Dr. Martin Schell, head of OpTecBB and director of the Fraunhofer HHI said “Together, we want to strengthen cooperation in research and development, promote the mutual exchange of expertise, thus improving our position in the worldwide competition for excellence.”
TU Berlin itself as host institution provided two glimpses into the future of photonics and quantum research. Firstly, its projects working to smooth the path to a global quantum Internet and open up collaboration with the Dutch QuantumDelta cluster, and secondly the unique, Berlin-wide Berlin School of Optical Sciences and Quantum Technologies doctoral program, which trains the next generation of top researchers and develops strong connections with Dutch partner institutions.
The economic potential of photonics in the Berlin region was demonstrated by the 35 scientific institutions and 400 businesses active in this area. Among these was traditional optics manufacturer Berliner Glas. Founded in 1952, Berliner Glas was acquired by ASML, a Dutch-based world leader in production systems in the semiconductor industry, last November 2020. Both companies attended the event in the Atrium and presented their latest technologies for chip production as well as their current plans for expansion in Berlin, including new infrastructures and measures to increase the 1000-strong workforce (400 more high-tech jobs to be staffed in the next 18 months).
The Fraunhofer Heinrich Hertz Institute (HHI) provided examples for how research can be put into practice and how German-Dutch cooperation is creating a leap forward in European Photonics innovation. The miniaturized BB84 transmitter chips developed by researchers at the HHI are so small that they can only be viewed under a microscope, but their impact could scarcely be greater as they provide the necessary technology to make communications and IT systems faster, more energy efficient and more secure. For very precise tunable lasers, the researchers are working closely with Dutch start-up LioniX as well as PhotonDelta, a consortium committed to developing strong European networks in the areas of photonics research.

news-2181Tue, 09 Feb 2021 12:00:00 +0100Laser Technology for Agriculture 4.0 climate change, uncertainties in food security, and pressure to preserve resources, agriculture is facing difficult tasks. To meet these challenges with cost-effective and intelligent electronic solutions, researchers at Fraunhofer IZM are working with partners to combine smart system integration with sensor technology, thus enabling the leap to Agriculture 4.0. In an earlier project they developed a laser that uses optical detection and AI evaluation to prevent infestation with harmful insects in warehouses and that is intended to replace the usual fumigation.Between the cultivation of grain and its consumption lies the real work of farmers. The growth of the plants must be continually monitored, the soil quality checked, and harmful insects eliminated — processes that cost both time and money. To modernize them, Fraunhofer IZM and the TU Berlin are involved in the ZIM network “AgriPhotonik” which brings together 29 German and Israeli partners from industry and research to establish digital processes in agriculture by using the potential of agricultural technology and photonics. The network management is handled by the OpTecBB competence network.

In the precursor project “Insect Laser”, supported by the Federal Office for Agriculture and Food and partners, a solution was developed at Fraunhofer IZM to protect the agricultural stock from contamination by grain weevils and Indian meal moths. Though barely four millimeters long, these pests can cause significant economic damage and carry diseases.

It is common practice to fumigate storage spaces with chemicals only after an infestation with harmful insects. These chemicals, such as hydrogen phosphide, are deadly to the insects but can be used only sparingly. When used more frequently, residues on the stock can cause health hazards to humans and, above all, environmental pollution.

To reduce the use of chemical protective agents, the researchers at the Fraunhofer Institute for Reliability and Integration IZM set out to combine laser technology and automated image recognition to reliably ensure the safety of agricultural products. The project was coordinated by the Julius Kühn Institute in Berlin.

The researchers detect the moment of infestation before the pests can spread throughout the stocks. Using an image-processing method developed by the BTU Cottbus (Brandenburgische Technische Universität Cottbus), the small pests are detected on the surface of the supplies or on walls. An AI system then analyzes and classifies the insects and compares them against reference images. Such algorithms for image recognition are already established in countless applications. In this project, however, the wide variety of dimensions was especially challenging, since harmful insects that are only a few millimeters in size need to be reliably detected in the warehouses. This had to be taken into account in the design and production of the IZM laser system.

Once the position of a pest is known, a fine laser beam is directed to the relevant coordinates via radio by a scanner, rendering the corn weevil or Indian meal moth harmless. Because of the low temperature and intensity of the laser, the grains located underneath are unaffected.  By using a laser system, direct primary infestation is prevented, so that insects harmful to supplies do not spread in the first place.

The Fraunhofer IZM researchers in Berlin examined how different wavelengths and light beam intensities influenced the movement behavior of the pests and found that the infrared light had the lowest effect on the characteristic movement behavior used to identify the animals. The researchers were also significantly involved in developing the laser system, and initially created a laboratory setup. Following successful testing, they transferred this set-up into a compact insect laser system consisting of several units for use in test cells.

They also developed the interfaces for software and hardware between camera, laser, and scanner.

With these activities, Fraunhofer IZM is opening up to projects that will increase digitalization and automation in agriculture. In doing so, the researchers integrate optical sensors and electronic controls into unique systems and ensure that these can be manufactured efficiently and used sustainably.

news-2175Wed, 03 Feb 2021 15:09:13 +0100Instrument Systems: Measure what the human eye sees: optical testing of AR/VR headsets AR/VR with periscope lens enables two-eye measurement for AR/VR headsets, even under tight spatial constraints. Munich, February 2021 – Perfect user experience for AR/VR headsets calls for extensive, fast and highly accurate optical tests during production. In order to meet this specific challenge, Instrument Systems has developed the LumiTop AR/VR 2D imaging colorimeter. The LumiTop’s AR/VR lens simulates the human eye and measures color and luminance exactly as seen by the user. The unique periscope design enables synchronized two-eye measurements, and the proven LumiTop principle guarantees fast, traceable and highly accurate measurements. AR/VR devices are an exciting new way of visual interaction with the environment in real time. Besides the virtual display, the headsets contain several types of light sources and sensors that enable users to immerse themselves in the virtual world. To ensure a perfect user experience, extensive and highly accurate optical tests are necessary. Besides standard optical tests, new parameters that are specific to near-eye displays, e.g. eyebox dimensions, are critical for quality assurance. A uniform display is fundamental for an undisturbed viewing experience. Accurate luminance and colors are a basic requirement for natural perception. Contrast is important for good legibility of virtual text. Distortion of the image due to tolerances in the mechanical and optical setup have an immediate impact on the display quality and must be kept below the human perception threshold.
In order to meet these test requirements, the LumiTop AR/VR 2D imaging colorimeter designed by Instrument Systems has been optimized for the production testing of near-eye displays (NEDs). The AR/VR lens in the LumiTop simulates the human eye and measures color and luminance exactly as seen by the user. A wide camera field of view (120°), various pupil sizes and an adjustable focus distance facilitate a wide range of testing applications.
The unique periscope lens design guarantees easy access to the NED and enables an optimal measurement position, even under the tight spatial constraints of fully assembled headsets. A hardware trigger enables perfectly synchronized one-shot two-eye measurements with two LumiTops.
LumiTop AR/VR is also based on the proven LumiTop principle. While an RGB camera takes the image of the NED in one shot, a reference spectroradiometer corrects the results to yield highly accurate absolute luminance and color values. The measurement results are fully traceable to national standards and therefore allow low manufacturing tolerances, especially important for distributed manufacturing. Simultaneous measurement of a 2D image, spectrum and flicker makes LumiTop a very fast, comprehensive and highly accurate imaging light measurement device for AR/VR tasks in production. Instrument Systems also offers testing solutions for the IR sources (NIR LED, VCSEL) often used for gesture and object recognition within an AR/VR headset.

news-2147Mon, 05 Oct 2020 11:35:00 +0200Search for traces of microplastics in humans: New joint research project funded PlasMark project, which has been awarded 4.5 million Euros by the Federal Ministry of Education and Research, will start in October 2020 with the aim of investigating the consequences of microplastics in the human body. Methods from astrophysics will be applied. The multidisciplinary research team from the fields of physics, biochemistry, biology and pharmacy is focusing on the question of how label-free diagnostics of plastic particles is possible. "We focus on three different state-of-the-art technologies," explains Prof. Martin Roth from the innoFSPEC research centre at the Leibniz Institute for Astrophysics Potsdam (AIP). "In addition to confocal Raman spectroscopy and terahertz spectroscopy, which we know from the so-called body scanners at the airport, the suitability of multispectral light and electron microscopy for this purpose is being investigated.”

All three approaches - partly borrowed from astrophysics - are suitable for making statements about the chemical composition of a particle as well as visualising it. Raman spectroscopy take advantage of the fact that matter interacts with laser light, leaving behind a characteristic fingerprint - a spectrum in the scattered light. In this way it is also possible to assign the plastic particles to their original material - e.g. polyethylene, polystyrene or PVC. While this works well for sufficiently large pieces of plastic, the challenge for the team is to detect these fingerprints for small and minute particles. In addition, successfully scanning tissue samples with conventional Raman microscopes is very time-consuming and can take many hours to days. The innoFSPEC research centre at the AIP has set itself the goal of realising an imaging Raman spectroscopy setup that allows the identification of plastic particles within minutes or seconds. This is made possible by wide field spectrographs from astronomy - where this technique is used in observatories to save valuable observation time.

The joint project supports research at three Centres for Innovation Competence (ZIK) in the new federal states: ZIK plasmatis at the Leibniz Institute for Plasma Research and Technology Greifswald (INP), ZIK HIKE at the University Medical School and University of Greifswald and ZIK innoFSPEC at the Leibniz Institute for Astrophysics in Potsdam (AIP). The first results are expected to be available in two years' time in order to be able to better answer the question to what extent the contamination of the environment and thus of the human body with microplastic particles is one of the causes of neurodegenerative diseases, cardiovascular diseases or even cancer.

The key areas of research at the Leibniz Institute for Astrophysics Potsdam (AIP) are cosmic magnetic fields and extragalactic astrophysics. A considerable part of the institute's efforts aim at the development of research technology in the fields of spectroscopy, robotic telescopes, and e-science. The AIP is the successor of the Berlin Observatory founded in 1700 and of the Astrophysical Observatory of Potsdam founded in 1874.

news-2045Thu, 10 Sep 2020 14:02:32 +0200GIGAHERTZ: UVC Radiometer for Germicidal UV Sources including 222nm Excimer Lamps new X1-1-UV-3727 radiometer is designed to accurately measure the far-UVC irradiance or dose produced by 222nm excimer lamps. This is in addition to the measurement of other germicidal UV source types including low pressure Hg lamps and UV LEDs. Each meter has a wide dynamic range and is supplied with a traceable calibration certificate from the ISO-17025 accredited Gigahertz-Optik laboratory. Far-UVC radiation, such as the 222nm produced by Kr-Cl excimer lamps, has been the subject of many studies and is known to be effective against a wide range of pathogens.  Significantly, it is also thought to offer less photobiological hazard because far-UVC light cannot penetrate human skin as deeply as the longer wavelength UV radiation produced by low pressure Hg lamps and UVC LEDs.

The X-1-1-UV-3727 radiometer measures UV-C irradiance over a very wide dynamic range from 0.002 µW / cm² to 1000 mW / cm² which permits the investigation of both germicidal efficacy as well as hazard.  It is supplied with calibrations at 222 nm for excimer lamps, 254 nm for low pressure Hg lamps, and wavelength dependent calibration factors given in 5 nm increments 250 nm to 300 nm for UV LEDs. The detector’s flat spectral responsivity ensures lowest measurement uncertainty irrespective of the precise wavelength of UV LEDs which inevitably varies according to operating conditions and manufacturing tolerances.

The handheld meter provides a real time display of irradiance (mW / cm²) or dose (mJ / cm²) and includes a peak-hold function. The device may also be operated via its USB interface with optional S-X1 software. To correctly measure irradiance the detector’s entrance optic is a diffuser with a cosine field of view. The detector is pre-aged to significantly reduce solarization effects that results from long term exposure to UV radiation.

Gigahertz-Optik operates an extensive calibration facility that is DIN EN ISO / IEC 17025 accredited. In addition to the absolute radiometric calibration, every UV radiometer produced by Gigahertz-Optik is individually calibrated with regard to its relative spectral responsivity. In accordance with CIE 220:2016 this enables spectral mismatch error to be corrected for, thereby reducing the overall measurement uncertainty.

news-2035Mon, 31 Aug 2020 15:27:42 +0200SphereOptics: New UV Raman Spectrometer partner Wasatch Photonics is proud to announce the addition of a compact, costeffective UV Raman spectrometer to its family of modular Raman spectroscopy products. The WP248 Raman spectrometer expands on the company’s existing range of high sensitivity research and OEM Raman solutions spanning 405 to 1064 nm. Use of UV excitation makes the WP 248 ideal for fluorescence-free Raman spectroscopy, as well as UV resonance Raman (UVRR) to enhance sensitivity and selectivity. Applications range from materials analysis to UVRR studies of structure and dynamics in biomolecules such as proteins and nucleic acids.The WP 248 is a stand-alone UV Raman spectrometer with free space input and an f/2.0 numerical aperture for superior signal collection and high throughput detection. It covers a range of 400 to 3200 cm-1 with 14 cm-1 resolution, and employs a UV-enhanced CCD for detection. It is designed for use with a compact 248.6 nm NeCu laser, and comes with a triggering cable to synchronize acquisition with the laser. Data collection and spectrometer control is included through the company’s own ENLIGHTEN™ operating software and software development kits C/C++, C#, Python, LabVIEW, MATLAB, and other languages.
UV Raman offers several unique advantages for applications that may be challenging using visible and NIR excitation wavelengths. By exciting and collecting Raman spectra at wavelengths below 300 nm, UV Raman avoids interfering signal caused by native autofluorescence from the sample. This improves signal to noise for highly fluorescing samples, and enables trace detection of analytes within a more complex sample matrix.
Careful choice of excitation wavelength can also enable UV resonance Raman (UVRR) spectroscopy, which offers 102-106 signal enhancement for select analytes, or specific subgroups within biomolecules. This combination of enhanced sensitivity and selectivity is invaluable in the study of structure, dynamics, and interactions of proteins and nucleic acids, and has contributed to our understanding of protein folding.
Wasatch Photonics’ new WP 248 Raman spectrometer offers high sensitivity in a compact footprint for modular UV Raman and UVRR spectroscopy. It covers both the fingerprint and functional range with choice of uncooled and TEC-regulated detector, and can be user-reconfigured with choice of free-space input or integrated lens.

news-2013Mon, 03 Aug 2020 09:23:40 +0200TOPTICA: World Record CEP-Noise its first demonstration the frequency comb has evolved into a versatile optical tool. Today, TOPTICA’s Difference Frequency Comb DFC enables applications like high resolution spectroscopy, optical clocks or low-noise microwave generation.20 years ago, John L. Hall (Nobel laureate together with Theodor Hänsch “for their contributions to the development of laser-based precision spectroscopy, including the optical frequency comb technique”) and coworkers published a seminal paper1, in which they first reported on the stabilization of the carrier-envelope phase of the pulses of a femtosecond mode-locked laser.
With the Difference Frequency Comb DFC, TOPTICA has taken the next step. Using difference-frequency generation (DFG), the carrier-envelope phase is now stabilized for each pulse individually with an intrinsic locking bandwidth identical to the repetition rate of 200 MHz. The result is an unprecedented low level of carrier-envelope phase noise of only 135 mrad integrated from 70 mHz to 40 MHz. The DFG process is key for achieving such high-end performance. It also delivers a new level of robustness, which allows for reliable long-term operation.
Moreover, the DFC product line offers a very user-friendly control interface and comes in a compact 19-inch format. The unique combination of these properties turn it into the ideal source for the most demanding comb applications no matter if you are a comb expert or if you are discovering the field.

news-1972Mon, 22 Jun 2020 09:36:29 +0200Gigahertz-Optik: Innovative spectrometer system for determining the scattering and absorption coefficients of turbid media the new and unique SphereSpectro 150H spectrometer system, Gigahertz-Optik offers a solution for simultaneously determining the spectral absorption and scattering coefficients for scattering samples. Conventional spectrophotometers (also called transmission spectrometers or absorption spectrometers) are used to determine the absorption coefficient of clear or colored media. . In a similar way to these conventional systems, the SphereSpectro 150H is used to determine the spectral absorption coefficient of scattering media. To do this, the sample is illuminated and the transmitted as well as the reflected light is measured and evaluated in a differentiated manner using radiative transfer theory. For clear samples the absorption coefficient is determined based on Beer-Lambert's law. However, if the sample exhibits scattering (i.e turbid or translucent samples), the entire physical process must be taken into account, i.e. a combination of scattering and absorption properties.

With the innovative SphereSpectro 150H spectrometer system from Gigahertz-Optik the absolute absorption coefficient can now also be determined for scattering media independent of the scattering properties of the turbid medium. At the same time, the effective scattering coefficient of the sample is determined, which provides additional information about the microstructure of the sample. This is a unique feature, which is not otherwise available on the market. The determined absorption coefficient is identical with the absorption coefficient determined conventionally for clear media and can be used for content determinations, for example. The SphereSpectro 150H uses an integrating sphere to measure the total reflected and transmitted light of an illuminated sample. From these two quantities, the absorption coefficient and the effective scattering coefficient are calculated based on the radiative transfer equation.

The SphereSpectro 150H covers the wavelength range between 200 nm and 2150 nm. Modular versions are also available for sub-ranges within this entire spectral range. The unique measuring system is also characterized by simple operation, short measurement times and a large sample chamber with optimized sample holder whilst keeping overall size to a minimum.

Additionally, the device has sufficient sensitivity to detect if undesired exposure poses a photobiological safety risk to users.UVGI is a sterilization method that uses UV-C light to break down microorganisms such as viruses and bacteria by altering their DNA and RNA, rendering them unable to replicate. The germicidal effectiveness of UV-C radiation depends on its dose (µJ / cm2) and wavelength. The dose is determined by measuring the irradiance (µW / cm2) and duration of exposure. The effectiveness of germicidal activity is wavelength dependent with a maximum around 265 nm which makes the potential germicidal efficacy of available UV-C LEDs greater than 254 nm emission Hg lamps.

The X-1-1-UV-3726 radiometer measures UV-C irradiance over a very wide dynamic range to beyond 100 mW / cm² with a resolution of 0.0001 µW / cm².  It is calibrated for its spectral responsivity from 250 nm to 300 nm. Wavelength dependent calibration factors given in 5 nm increments are incorporated for measuring UV LEDs with known nominal wavelength. Additionally, a 254 nm calibration is included for Hg lamps as well as a general purpose 260 nm to 290 nm calibration for non-specific UV-C LEDs.

The X1-1-UV-3726 offers sufficient sensitivity to check for safety compliance and the effectiveness of personal protection equipment (PPE) in accordance with the accepted occupational exposure limit to actinic UV (ICNIRP). This requires irradiance levels to be < 0.2 µW/cm2 at 254 nm and < 0.1 µW/cm2 at 270 nm over 8 hour’s exposure.

The handheld meter provides a real time display of irradiance or dose and includes a peak-hold function. The device may also be operated via its USB interface. Each meter is supplied with a traceable calibration certificate from the Gigahertz-Optik laboratory.

These companies have applied for exemption from the RoHS regulations in Brussels.

The EU directive 2011/65/EU on the restriction of the use of certain hazardous substances in electrical and electronic equipment (RoHS 2) contains a list of chemical elements and compounds that may no longer be used in electronic products. This includes lead in concentrations above 0.1%. The legislators are primarily concerned with tin solder that contains lead. However, this heavy metal is also a crucial component in the PbS and PbSe detectors manufactured by the LASER COMPONENTS Detector Group.

Manufacturers can apply for exemptions from this rule if a product is indispensable for certain applications. Annex IV, point 1c of the directive explicitly mentions lead used in infrared detectors. Together with its customers, LASER COMPONENTS has formed a consortium that has been able to prove that an alternative to using lead salt detectors in certain areas is not available.

“Many SMEs would simply be overwhelmed with the burden of EU law if they tried to take it on themselves,” says Sven Schreiber, who coordinated the activities at LASER COMPONENTS. “As a well-known player in the international detector market, we have taken the initiative. We are confident that our application will be granted. This would benefit all market participants for another seven years. At that time, the exemption will be renewed.”

news-1811Fri, 24 Jan 2020 20:57:00 +0100Instrument Systems: New spectroradiometer speeds up LED production new CAS 125 spectroradiometer with CMOS sensor is designed to maximize production efficiency and offers a unique “Recipe” mode that enables time-optimized control. Munich, January 2020 – Product life cycles are getting shorter all the time. The corresponding increase in the number of product variants presents manufacturing companies with new challenges. Production lines need to be faster and more complex, yet also more user-friendly. Instrument Systems – a well-known manufacturer of light measurement technology – works closely with its customers in the field of LED production to develop modular and flexible components for quality inspection in mass production environments. For the new spectroradiometer CAS 125, Instrument Systems has therefore focused on production-related applications for LEDs in the spectral range between 200 and 1100 nm. Instrument Systems will be presenting its new measurement device for the first time at booth 716 of Strategies in Light trade show, which will be held in San Diego from 11 to 13 February, 2020.

For the CAS 125 spectroradiometer, Instrument Systems decided to equip the device with a CMOS sensor that is linked to a specially developed electronic readout circuit. This combination enables very low measurement times of 0.01 milliseconds while simultaneously optimizing long-term stability. The spectrograph design is based on the high-end CAS 140D device, which is already well established in the market. This gives the CAS 125 a level of optical performance comparable to that of the CAS 140D in terms of both stray light suppression and optical throughput. The device-specific electronic readout circuit enables time-optimized control of the spectrometer through parameterization of successive measurements in Recipe mode on the CAS 125. This eliminates the time-consuming step of communicating with the PC to initialize each subsequent stage of the measurement process.

Another unique feature of the CAS 125 sensor is its built-in temperature stabilization feature. This results in dark current behavior that is independent of the ambient conditions, enabling the CAS 125 to ensure optimum long-term stability even in environments where temperatures fluctuate. A further highlight is the ability to parameterize the flash trigger. This element helps users synchronize the spectrometer with other system components, for example by triggering a photodiode measurement.

These key features – temperature stabilization and Recipe mode – are two of the CAS 125’s unique selling points. They significantly improve automated processes in LED production, thus boosting productivity.

This is the first time that the two-photon polymerization (2PP) process of pioneer MPO is used worldwide for the industrial production of miniaturized components in a pay-per-use model.The lasers manufactured by nanoplus are used for high-precision measurements in industry and research. In the market for infrared sensors, the manufacturers of the sensors so far had the problem that they had to perform complex packaging and alignment steps. This increases the production costs and prevents miniaturized sensors required by the market. Multiphoton Optics’ High Precision 3D Printing process, also known as 3D Lithography or Direct Laser Writing, additively manufactures the required microoptics directly onto the laser facets.

“Multiphoton Optics’ technology allows us to inexpensively offer miniaturized laser sources for infrared sensing. This allows our customers to save time and money and build much more compact sensors.”, says Dr. Johannes Koeth, CEO of nanoplus.

The high-precision 3D printing from Multiphoton Optics is integrated into the existing production processes of nanoplus.

Dr. Ruth Houbertz, CEO & Managing Director of MPO, says: “In more than 15 years of collaboration with industrial customers, we have brought two-photon polymerization from research laboratories to practical industrial manufacturing. With our pay-per-use model, users drastically reduce their time to market, minimize their investment costs, and pay per manufactured quantities.“

news-1723Mon, 14 Oct 2019 12:13:42 +0200Fraunhofer IZM is putting the electric car in the fast lane carbide has been undergoing testing for several years within the research sector as a promising alternative material in the semiconductor industry. In the SiC Modul project, the power semiconductor is now to be put on the road to industrial production. Skeptics of electromobility have raised critical questions, such as how fast an electric car can be driven and the maximum distances it can cover. That depends on the built-in power electronics – the heart of electromobility, if you will. Three factors are decisive when it comes to the installation of power electronics: space, weight, and efficiency. The semiconductor material silicon carbide (SiC) meets these conditions because it has a higher degree of efficiency and can or must be installed more compactly than conventional semiconductors made of silicon only.

Although some electric cars already run on SiC semiconductors, there is still considerable potential here to fully exploit the efficiency of the SiC semiconductor material. The key to the success of SiC lies in the packaging of the semiconductors. In order to be able to use the material for large-scale industrial production, the SiC Modul project will take industrial framework conditions into consideration right from the start. For example, the module being developed within the project is based on a traditional printed circuit board design that has already been established in industry and is easy to implement.

At the same time, the module will include the latest lessons learned from research: the semiconductor is not contacted with a wire bond connection, but is embedded directly into the circuit via a galvanically produced copper contact, meaning that the cable can be shortened and the power routing can be optimized. The potential customer is also involved in the development process: in the first year of the project, a requirement specification was drawn up in which the electrical, thermal, and performance requirements for the module and the semiconductors were defined. The specifications that the product must meet were drawn up and agreed in close collaboration with users such as automobile manufacturers, component suppliers, and component manufacturers.

Lars Böttcher is group manager at Fraunhofer IZM and subproject manager for the SiC project. He explains: “We are going beyond general feasibility,” because the intention is that the project should develop more than just a prototype. The aim is therefore to put both the new semiconductor material silicon carbide and the embedment technology towards series production.

However, none of these comparisons does the concept justice. Start-A-Factory (SAF for short) combines device infrastructure with a working environment designed to meet the specific requirements of hardware start-ups. Embedded in a network of Fraunhofer IZM specialists and other partners, the SAF environment employs project-based partnerships and state-of-the-art systems, enabling development teams to go quickly from initial idea to professional prototype.

Now that all the elements are in place and ready for use, the creators have organised a walk-around event. In addition to workshops showcasing the individual stages of microelectronic hardware development, the key notes were a special highlight. Mike Richardson, Founder and Technical Advisor – but also a container user himself at SAF – explained to the audience what the nerds of the future will look like. “The special thing about a tech dork is the mix of a nerd and a communicative and social person.”

SAF also illustrates that conducting research and establishing a start-up in the hardware sector need not be boring. The six containers, which resemble an industrial production facility, will be made available as work spaces for teams of developers who wish to develop hardware and – most importantly – prototypes as part of a joint project. An impressive range of equipment, from pick-and-place machines to 3D printers, offers developers the opportunity to turn their ideas into products.

The guests and partners on site were thrilled with SAF. Participants enjoyed a lively exchange as part of a relaxed get-together at the grill, discussing their journey of technological discovery in addition to the versatility of this special infrastructure environment and the possibilities it will offer start-ups, SMEs and other teams of developers. New partners and container users are already lining up for future partnerships.


Research of practical utility lies at the heart of all activities pursued by the Fraunhofer-Gesellschaft. At present, it maintains 72 institutes and research units. The majority of the 26,600 staff are qualified scientists and engineers, who work with an annual research budget of 2.6 billion euros. Of this sum, 2.2 billion euros is generated through contract research. More than 70 percent of the Fraunhofer-Gesellschaft’s contract research revenue is derived from contracts with industry and from publicly financed research projects. Almost 30 percent is contributed by the German federal and state governments in the form of base funding, enabling the institutes to work ahead on solutions to problems that will not become acutely relevant to industry and society until five or ten years from now.

The Group company SwissOptic AG in Heerbrugg, Switzerland, will be supported by six new trainees. An intensive induction process makes it easier for new talent to start working at this leading supplier of optical key components, assemblies, and systems.Of these professional beginners, four decided to pursue a dual study program in design and production as well as business administration/industry. Ten started their industrial and technical training as a precision optician and two as a machining technician. The Berliner Glas Group currently has 34 apprentices and dual program students on staff.

Training enjoys a special status, which is demonstrated by the repeat “Excellent Training Quality” award from the IHK. The Group’s excellent training quality was confirmed for the first time in 2017. This IHK seal is an acknowledgment and recognition of the extensive commitment of the Berliner Glas Group as an educational enterprise. However, the Group invests in much more than its young talent; in 2018 Berliner Glas created its own training and learning environment with its modern training center in Berlin.During their training, new employees will pass through many departments and acquire valuable practical experience. They learn the theoretical basis at vocational schools and university. In addition to professional qualification, the Berliner Glas Group is also focused on the personal development of the apprentices and dual program students.

“We place great emphasis on training our specialists ourselves, and that is what we are doing this year, too. This is of strategic importance to us in light of the company’s steady growth in recent years and the existing shortage of skilled workers,” says HR manager Dr. Regina Draheim-Krieg.

The application and selection phase for the 2020 training year has already begun at the Berliner Glas Group. Training spots will be provided in the coming year as well. More information on educational options at Berliner Glas and SwissOptic can be found on their respective career websites: and

news-1679Tue, 20 Aug 2019 10:41:15 +0200Making small intestine endoscopy faster with a pill-sized high-tech camera resolution, sharper images, and more efficient diagnostic processes – this is the promise of an endoscopy capsule developed by Fraunhofer IZM to allow more detailed small intestine diagnostics.2001 the first endoscopic capsule took its journey through the small intestine of a human patient. With its miniature camera, the capsule captured thousands of images of the small bowel. six meters of winding intestine had long prevented normal endoscopic diagnostics in this region of the digestive system. Since this breakthrough, capsule endoscopy has become the norm, made possible with a range of different capsule designs.

Traditional capsule endoscopy, however, suffers from one key limitation: Images are captured on a strictly timed sequence, whether the capsule has moved or not. This can create a glut of redundant images that needs to be sifted and filtered by hand. With image capture responding to actual movement, the amount of redundant data can be minimized, with up to a third fewer images to sort through.

The Endotrace research project has now developed a novel endoscopic capsule technology that promises to avoid redundant data. Supported with €1.2 million in funding from the German Ministry of Education and Research, the project was brought to a successful conclusion in November 2018, with the Fraunhofer Institute for Reliability and Microintegration IZM, Ocesco Endoscopy AG, and AMS presenting the fruits of their labor: a ‘treat-sized’ capsule whose unassuming exterior hides cutting-edge technology on the inside. With no fewer than five cameras, a tracer, and a memory module on board, the tiny capsule still has room for its battery pack and an LED light.

How does it know when and where to capture an image? The built-in controller responds to minute changes in the villi that line the intestinal walls and triggers the camera after the capsule has moved a tenth of an inch. Instead of several thousand repetitive images, the Endotrace capsule produces less than half, but far more meaningful data and helps speed up the diagnostic process. This promises a faster reaction to acute conditions like gastrointestinal bleeding. However, it will still take some time before the first capsule will go on its journey through an actual patient’s digestive system: While the technology is ready, the system still has to go through the long medical approval process.

Manuel Seckel, Project Leader at Fraunhofer IZM, explains: “Endotrace is a passion project for me! Endoscopic diagnostics helps save lives – and we are making it that little bit easier and better.”

Bavaria is well positioned for the future with its outstanding infrastructure in terms of laser technology. Laser sounds like the future – and rightly so. Laser technology has not only been directly linked to the technologies of the future since today. We have long been familiar with lasers from printers and barcode readers. They were once the technology of the future. On the other hand, the future is now with holography or data transmission using optical fibres. The same also applies to the promising additives manufacturing industry: a product is manufactured by applying a starting material layer by layer using a three-dimensional computer model. The material binds during the process and everyday objects or components for industry are ready.
