... translating ideas into innovation

Welcome to the Ferdinand-Braun-Institut, Leibniz-Institut fuer Hoechstfrequenztechnik!

hybrid-integrated diode laser modules for display technology

We research cutting-edge technologies in the fields of microwave technology and optoelectronics. For customers in industry and science we provide high-frequency devices and circuits for communication and sensor technology as well as high-power diode lasers for materials processing, laser technology, medical technology and high precision metrology.

As a competence center for III/V-compound semiconductors we operate industry-compatible and flexible clean room laboratories with 2"-4" gas phase epitaxy units and a 2"-4" process line.

Fast, efficient switching – thanks to HiPoSwitch

Power converters use power transistor switches as key components to accomplish power conversion. Lightning-fast semiconductor switches able to operate these kinds of converters more efficiently have now been developed in the recently completed EU group project called HiPoSwitch.

Fast, efficient switching – thanks to HiPoSwitch

HiPoSwitch, an EU group-project, has successfully developed lightning-fast, high-efficiency gallium nitride power switches. These are essential for producing energy-efficient, compact, and light-weight power converters that make electrical energy more useable. The market potential is enormous, since these converters are found in nearly every electronic device.

Thermal characterization of AlGaN/GaN HEMTs on Si and n-SiC substrates

Channel temperature characterization of AlGaN/GaN devices is an important feature for reliability estimation and assessment of power switching losses. We present here a method to thermally characterize large AlGaN/GaN HFETs based on pulsed electrical measurements, performed in cooperation with TU Berlin. The results have then been correlated to ANSYS simulations.
