78 Cluster Report Optics and Photonics – Microsystems Technology components as controls. The flexibly adaptable sources are indispensable components in such applications as LiDAR (Light Detecting and Ranging), the laser-based radar required for autonomous cars and robots. Arquimea Deutschland GmbH, a subsidiary of the Spanish company Arquimea, is also working on space applications. In Frankfurt (Oder), it is developing radiation-hard circuits for space technology. The high-quality chips are then produced in smaller quantities at IHP. www.arquimea.com Microcamera with embedded passive and active components. The high integration density allows the contents of the image to be evaluated within the camera module. © Fraunhofer IZM/Volker Mai The Ferdinand-Braun-Institut, Leibniz-Institut fuer Hoechstfrequenztechnik (FBH) offers microsystems for custom applications from medicine to space technology. For example, a flexible ophthalmology technology platform was developed at FBH. At its core, infrared laser light is efficiently converted to the yellow frequency range: the source delivers more than 2 W at 561 nm. The FBH also uses the same principle with different wavelengths for sensor and analytical applications. Compact measuring systems are created that deliver results quickly and reliably in situ. An important aspect in the cooperation between science and industry is the spin-off of innovative companies from research institutes. One example is GOLARES GmbH. GOLARES was founded out of the Leibniz Institute for Crystal Growth (IKZ) in Berlin-Adlershof. The core idea of the company is an innovative plasma source that allows low-damage processing through low-ion energies and conformal coating with conductive and insulating layers at high rates and low tension. The company offers consulting services on such as processes as well as coating and microstructuring of optoelectronic and microelectronic devices. In March 2017, the two founders were awarded the Leibniz Start-up Prize. www.golares.com FBH’s laser systems for use in outer space also offer the highest integration densities on the smallest possible surface area. They work reliably even under adverse conditions such as space radiation, large thermal differences, or mechanical loads during rocket launch. FBH developed an ultra-precise microintegration assembly for this purpose. It offers positioning tolerances below 100 nm. www.fbh-berlin.com In addition, research is being conducted into new, compact diode laser sources that deliver high-precision pulses in the pico- and nanosecond range with high beam quality. Among other things, they use optimised HF microwave electronic Precision assembly of a fibre-coupled diode laser module for space applications at FBH © FBH/schurian.com

Cluster Report Optics and Photonics – Microsystems Technology 79 SMEs Are Shaping Microsystems Technology Sensors, actuators, signal processing Industry 4.0 is based on a network of sensors. This image alone gives an idea of the demands made on modern sensors today: they need to be small, robust, and yet precise. They should last a long time and their price as low as possible. Their development takes place in a highly technical environment that combines intensive research with a high-volume industry. Both fields are well represented in Berlin Brandenburg; indeed, local companies are among the world’s top companies in their respective fields. First Sensor AG is one of the world’s leading suppliers in the field of sensor technology. With almost 800 employees (as of the end of 2017), the company develops and manufactures standard sensors and customer-specific solutions for the growing industrial, medical, and mobility markets. For example, the company supplies avalanche photodiodes (APDs) for LiDAR systems to leading companies such as the American manufacture. V.lodyne. The long-standing partnership was further strengthened in 2017 with a standing order worth several million dollars. Today’s First Sensor AG started in 1991 as Silicon Sensor GmbH at the traditional industrial location of Berlin-Oberschöneweide. Its vision was to supply the reunited technology market of Germany with innovative sensors. Today, it is a globally active company with sales in the millions offering goods and services along the entire value chain from sensor chips to sensors and complex sensor systems. www.first-sensor.com/en First Sensor creates products ranging from chips to complex sensor systems. © First Sensor AG Other major players have production facilities in Berlin Brandenburg. For example, Pepperl + Fuchs GmbH, a specialist for proximity, acceleration, and ultrasonic sensors, offers a wide range of sensors in image processing and positioning aids. In 2017, approx. 6,000 people were employed at various locations in Germany, the United States, Singapore, Hungary, India, Indonesia, Vietnam, and the Czech Republic. One of its locations is in Berlin, the result of a takeover of Visolux company in 2000. www.pepperl-fuchs.com Avalanche photodiodes are a decisive component in LiDAR systems for autonomous vehicles. © First Sensor AG Another family-owned business trading internationally with its expertise in sensor technology, rotary encoders, measuring instruments, as well as components for automated image processing is the Baumer Group, headquartered in Switzerland. It is represented by the Baumer Hübner GmbH in Berlin- as a competence centre for encoders and
