... 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.


LayTec metrology speeds up process development on 100mm semi-polar (11-22) GaN on r-plane PSS

At the 17th US Biennial Workshop on Organometallic Vapor Phase Epitaxy (OMVPE-17) in BigSky, Montana, USA (2-7 August), Dr Frank Brunner of FBH (Ferdinand-Braun-Institut) of Berlin, Germany presented his latest results on the growth of semi-polar (11-22)-oriented gallium nitride (GaN) on r-plane patterned sapphire substrate (r-PSS).

Handheld Raman probe with implemented dual-wavelength diode laser at 785 nm for in situ SERDS

Raman spectroscopy is a powerful optical measurement technique for the analysis of various organic and inorganic samples. For Raman measurements with interferences such as fluorescence and daylight the Raman signals can be separated using Shifted Excitation Raman Difference Spectroscopy (SERDS). For mobile use, the FBH has now developed a compact handheld Raman probe with implemented dual-wavelength diode laser emitting at 785 nm as excitation light source for SERDS, and its application has been successfully demonstrated.
