... 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.


Top score - FBH positively evaluated and recommended for further funding

After the positive evaluation process, the Senate of the Leibniz Association recommended the Ferdinand-Braun-Institut for further joint funding by the federal and state authorities.

New in-situ analysis options for plasma etch processes at FBH

Dry chemical etching by means of highly reactive plasmas is one of the most important structuring methods in semiconductor industry. Within a cooperation of FBH and the company Laytec the impact of process parameters on the wafer bow could be analyzed for the first time directly in a plasma etching chamber using a modified curvature sensor. As a result, the etch parameters have been optimized in such a way that the bow caused by the process could be minimized, the process time decreased, and the yield increased.

Compact diode laser modules with single-mode fiber output in the multi-watt power range

Within the InnoProfile-Transfer joint research project "FaBriDi", the Ferdinand-Braun-Institut (FBH) develops fiber-coupled demonstrators for unrestricted industrial use. Recently, a butterfly module with a footprint of less than 10 cm2 has been successfully demonstrated, delivering multi-watt laser light with a narrow-band spectrum and high efficiency.
