64 Cluster Report Optics and Photonics – Optical Analytics the leading manufacturers of THz detectors in the frequency range from 700 GHz to 5 THz, but above all customers working in the research and development of THz systems and their users all over the world. In addition, a further measuring station with a state-of-the-art fibre-coupled THz TDS system from Fraunhofer HHI permits precise characterisation of material properties (transmission, reflection, and absorption) in the THz spectral range. SLT’s pyroelectric THz detectors are the basis for the first calibrated THz reference material for use in precisely measuring transmission and reflection. In addition, the PTB in Berlin-Adlershof operates the Metrology Light Source electron storage ring, which can generate coherent THz radiation. PTB carries out spectroscopic work in the THz spectral range on a dedicated THz beam tube, partly as part of its several partnerships. Beyond THz ... is where the radar range begins. What is traditionally associated with large rotating antennas at airports or on ships can now be accommodated on a microchip. Such technology was developed at IHP in Frankfurt (Oder) and brought to market by Silicon Radar GmbH. Its high-frequency switching is used in radar solutions, phased array systems, and wireless communication applications. Silicon Radar is developing customer-specific ASICs and standard components in the frequency range from 10 GHz (X-band) to 200 GHz and beyond. These miniature radar systems, which can be used for precise distance measurements or as fill level sensors, were awarded with the Brandenburg Future Prize in 2016. www.siliconradar.de www.ptb.de/cms/en/ptb/fachabteilungen/abt7/fb-73/ag-734.html Promoting collaboration Berlin is a popular place to go for international research in the field of THz waves. And collaboration within the region itself is helping to ensure success in national and international competition. One example is a partnership between Berlin-based eagleyard Photonics GmbH and the DLR, FBH, Humboldt University, and PDI to develop compact THz quantum cascade lasers for spectroscopic applications. This has resulted in the world’s most compact THz laser system.

The special feature here is the material: the core of the platform consists of a chip with optical waveguides made of polymer material, which can accommodate further passive elements such as glass fibres, thin-film filters, and micro-optics as well as active components such as photodiodes or laser chips (see chapter 2.3 “Photonics and Quantum Technology for Communication and Sensors”). www.polyphotonics-berlin.de
