Mit Sandwich-Chips zu hoher Leistung und Frequenz
/en/media-center/press-releases/mit-sandwich-chips-zu-hoher-leistung-und-frequenz
Even in special fields such as semiconductor technology seperate worlds exist: scientists often work independently on silicon-based CMOS circuits and III-V semiconductors, reports Prof. Wolfgang…
Wavelength-stabilized lasers with surface Bragg grating
/en/research/research-news/wavelength-stabilized-lasers-with-surface-bragg-grating
FBH uses frequency-selective Bragg gratings for its diode lasers in order to achieve a low temperature dependence and a very narrow line width of the emitted laser light. With its newly…
Gelungener Technologietransfer: UV-Photodioden schließen Lücke in internationalen Märkten
/en/media-center/press-releases/gelungener-technologietransfer-uv-photodioden-schliessen-luecke-in-internationalen-maerkten
UV photo diodes based on silicon carbide (SiC) are core components in a variety of applications ranging from process monitoring to biomedical analysis. Due to the close cooperation between research…
Normally-off high-voltage GaN transistors with carbon-doped buffer
/en/research/research-news/normally-off-high-voltage-gan-transistors-with-carbon-doped-buffer
The normally-off p-GaN gate technology developed at FBH combines low leakage currents for the unbiased gate (0 V) in the off-state with high currents and low resistances in the on-state. For…
Improvement of Load-Pull Characterization of Microwave Power Transistors: Measurements with Modulated Signals
/en/research/research-news/improvement-of-load-pull-characterization-of-microwave-power-transistors-measurements-with-modulated-signals
Microwave power amplifiers in modern telecommunication systems have to work over large bandwidth with high peak-to-average-power-ratio signals. Dedicated source- and load-pull measurement setups…
Chip mounting technology for UV LEDs developed
/en/research/research-news/chip-mounting-technology-for-uv-leds-developed
So far, the works on UV LEDs focussed on the optimization of the epitaxial structures. By means of UV LEDs (wavelength approx. 320 nm) a technology has now been developed which allows to…
Powerful all-rounders: FBH’s laser modules in matchbox size
/en/media-center/press-releases/powerful-all-rounders-fbhs-laser-modules-in-matchbox-size
At Laser World of Photonics, the Ferdinand-Braun-Institut highlights its miniaturized laser beam sources which are suitable for a variety of applications, from material processing to display…
UV photodetectors based on AlGaN/GaN heterostructures for optical switching
/en/research/research-news/uv-photodetectors-based-on-algangan-heterostructures-for-optical-switching
Due to their blindness in the visible region (solar blind) and the radiation resistance, GaN-based UV photodetectors are highly demanded for many application. FBH developed such detectors…
Hybrid laser modules for the green spectral region with high output powers and high conversion efficiency
/en/research/research-news/hybrid-laser-modules-for-the-green-spectral-region-with-high-output-powers-and-high-conversion-efficiency
FBH systematically examines frequency doubling of diode lasers in bulk crystals, planar and channel waveguides. Comparison reveals that frequency doubling of diode lasers in planar waveguides…
Laser-assisted fabrication of vertical interconnects for AlGaN/GaN power transistors
/en/research/research-news/laser-assisted-fabrication-of-vertical-interconnects-for-algangan-power-transistors
Vertical integration plays a key role with regard to the increasing integration density of electronic devices. Vertical interconnect accesses (VIAs) from the device’s front through the substrate…
