The Ferdinand-Braun-Institut, Leibniz-Institut für Höchstfrequenztechnik (FBH), is one of the internationally leading institutes for applied research in microwaves and optoelectronics. Based on III-V semiconductors it manufactures high-frequency devices and circuits for communication and sensor technology. High-power diode lasers with excellent beam quality are produced for materials processing, laser technology, medical technology and high-precision metrology. FBH also conducts basic investigations on nitrides for future applications such as short-wave UV light sources or transistors for very high voltages.
