... translating ideas into innovation

Welcome to the Ferdinand-Braun-Institut, Leibniz-Institut fuer Hoechstfrequenztechnik!

ps light source with DBR laser & amplifier

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.


Mittendrin – Laser für 3D-Fernsehen

Wer künftig vor dem Fernseher sitzt, dem begegnen die Helden der Filme zum Greifen nah, dreidimensional und mitten im Raum. Ganz ohne lästige Spezialbrille und mit besserer Schärfe und Tiefenwirkung, als dies bisher schon möglich ist.

Reduced dislocation density – patterning of sapphire to fabricate templates for GaN/AlGaN epitaxy

Epitaxial growth of GaN/AlGaN layers for light emitters in the ultraviolet spectral range has increasingly attracted interest in recent years. To improve the internal quantum efficiency of such LEDs, epitaxial layers with reduced dislocation densities are required.  The FBH successfully fabricates patterned sapphire substrates and uses them for epitaxial lateral overgrowth (ELO), thus reducing strain and dislocation density in GaN/AlGaN layers.

Improved simulation of surface gratings of higher Bragg order

The spectral emission width of semiconductor lasers can be significantly reduced from typically a few nanometers down to the femtometer scale by implementing Bragg gratings into the resonator. These gratings can be realized cost-efficiently by etching V-shaped grooves into the semiconductor surface. However, their reflectivity could be predicted only insufficiently with simulations. Now, the FBH successfully expanded its simulation tools in a way that reflection spectra of V-shaped grooves can be calculated, too.

Humboldt awardee Prof. Russell Dupuis is visiting scientist at FBH

For his pioneering work in the epitaxy of III-V semiconductor nanostructures, Prof. Russell Dupuis has been honored with the Humboldt Research Award. The award is linked to a research stay at Technische Universität Berlin and Ferdinand-Braun-Institut. Prof. Dupuis was the first to develop high-performance metalorganic chemical vapor deposition (MOCVD) epitaxial growth systems for III-V compound semiconductors. He also demonstrated the first III-V solar cells and laser diodes grown by MOCVD.

Precision in mini format: new diode laser modules for Raman analytics and quantum sensors in space

The FBH presents selected diode laser modules at Laser Optics in Berlin from March, 18-20. These light sources include, among others, a diode laser for Raman spectroscopy emitting light alternatingly on two different wavelengths from one chip, thus significantly improving the detection limit of substances.
