About us

The Ferdinand-Braun-Institut (FBH) researches electronic and optical components, modules and systems based on III-V compound semiconductors. These devices are key enablers that address the needs of today’s society in fields like communications, energy, health, and mobility. In its optoelectronic field of expertise, FBH develops light sources from the near-infrared to the ultra-violet spectral range: high-power diode lasers with excellent beam quality, UV light sources, and hybrid laser modules. Applications range from medical technology, high-precision metrology and sensors to optical communications in space. The FBH covers the full range of capabilities, from design through fabrication to device characterization. The institute offers its international customer base tailored solutions and know-how as a one-stop agency – from design to ready-to-use modules and prototypes.

Stand-alone PC-controlled pulse laser source for LiDAR applications

Stand-alone PC-controlled pulse laser source for LiDAR applications

The FBH offers flexible laser sources delivering 200 ps to 20 ns pulses. For automotive LiDAR, wavelength-stabilized laser diodes have been developed emitting 5 ns pulses with 40 W pulse power near 905 nm with good beam quality and up to 85°C. 3-emitter laser chips, whose emission can easily be optically combined into one single spot, yield up to 100 W. Chips can be delivered with FBH driver or as stand-alone PC-controlled laser source. Further wavelengths and power ranges are possible.

Compact picosecond laser pulse source PLS 1030

Compact picosecond laser pulse source PLS 1030

The efficient all-in-one pulse laser system combines in-house developed optical and electronic semiconductor components, delivering ultra-short light pulses from 5-15 ps. It provides any desired repetition rate from the hertz to the MHz range; pulse peak performance reaches > 20 W output power. PLS 1030 is computer-operated and can thus be easily integrated into various laser systems. The PLS series allows integration of laser chips of any available wavelength from 630-1180 nm.

Portable Shifted Excitation Raman Difference Spectroscopy (SERDS) – from chips to applications

Portable Shifted Excitation Raman Difference Spectroscopy (SERDS) – from chips to applications

For rapid SERDS measurements, FBH has demonstrated monolithic dual-wavelength diode lasers emitting light alternatingly on two slightly different wavelengths. These Y-branch DBR diode lasers with electrically controlled micro-heaters implemented above the gratings provide dual-wavelength laser emission and wavelength tuning over several nanometers. Supplemented with battery power supply, electronic measurement equipment and a software interface, the system can be used for in situ measurements.
