About Ferdinand-Braun-Institut, Leibniz-Institut für Höchstfrequenztechnik

Ferdinand-Braun-Institut, Leibniz-Institut für Höchstfrequenztechnik (FBH) is an application-oriented research institute in the fields of high-frequency electronics, photonics, and quantum technologies. It researches and realizes electronic and optical components, modules, and systems based on compound semiconductors. In photonics, FBH develops light sources from the near-infrared to the ultra-violet spectral range: high-power diode lasers with excellent beam quality, UV light sources, and hybrid laser modules. Applications range from materials processing, medical technology, and high-precision metrology to optical communication in space. In quantum technologies, FBH translates laboratory-scale proof-of-concept experiments into robust, application-ready systems. Developments include quantum photonic components, hybrid micro-integrated modules, compact quantum sensors, diamond nanophotonic devices, and photonic quantum chips for secure communication, high-precision measurements, sensors, and computing platforms. In high-frequency electronics, FBH develops high-efficiency multi-functional microwave power amplifiers and millimeter-wave transceivers targeting energy-efficient wireless communications, radar, industrial sensing, and imaging. In addition, the institute specializes in heterogeneously integrated broadband MMICs and high-speed drivers for high-power diode lasers. Within Research Fab Microelectronics Germany (Forschungsfabrik Mikroelektronik Deutschland), FBH joined forces with 14 other German research institutes, thus offering the complete micro and nanoelectronics value chain as a one-stop-shop. The institute is a member of the Leibniz Association.
