... 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.

Demonstration of GaN-based near UV laser diodes

The FBH develops low-threshold GaN-based edge-emitting laser diodes emitting in the near ultraviolet spectral range. Based on previous developments of blue-violet InGaN quantum well laser diodes operating in cw mode, FBH succeeded in realizing laser structures emitting below 390 nm with threshold current densities as low as 2 kA/cm² in pulsed operation.

Watt-class semiconductor optical amplifiers based on ridge-waveguide structures

The FBH successfully developed an improved epitaxial structure leading to a very strong increase in power level of the ridge waveguide (RW) amplifier. Together with a CW operated master oscillator the power amplifier can be combined to a MOPA system, yielding spectrally stable as well as diffraction limited radiation in the watt range. Such laser sources are ideally suited for applications including non-linear frequency conversion and coherent optical communication.
