... 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.


Writing contest - make your text a song!

No matter if it is a poem, short story or a song text, the main point is that it is about light! With LichtBlicke a writing contest for secondary students as of grade 7 starts, ideally matching the International Year of Light.

Flip-chip – a promising mounting technology for THz applications

Flip-chip connections offer shorter interconnection paths as compared to wire bonding, thus enabling higher bandwidth. At the FBH, only recently miniaturized waveguide structures with highest precision have been fabricated on RF substrates , featuring -1 dB bandwidth at 250 GHz. Small-signal RF measurements of back-to-back flip-chip transitions showed an insertion loss below 1.0 dB per interconnect, and a return loss of more than 1  dB from DC up to 250 GHz. These figures are so far the best reported flip-chip mounts in this frequency range.

Narrowband GaN-based diode laser system for the generation of DUV laser light for Raman spectroscopy

At the FBH, a GaN-based high-power diode laser system with an optical output power of 400 mW and narrowband emission at 445 nm has been realized for the first time. By using an external cavity, the institute manged to reduce the spectral width to 20 pm (with a side-mode suppression of more than four orders of magnitude). Thus, the system is well-suited as pump source for nonlinear frequency conversion into the deep ultraviolet (DUV) spectral region.
