Compact light control unit for use in a low-SWaP strontium optical atomic clock
/forschung/forschungsnews/compact-light-control-unit-for-use-in-a-low-swap-strontium-optical-atomic-clock
Using FBH’s unique hybrid micro-integration technology, we realized a compact light control unit for laser beam conditioning in a transportable strontium-based optical atomic clock. Equipped with…
Improved stability of InGaN-based laser diodes by overcoming facet degradation
/forschung/forschungsnews/improved-stability-of-ingan-based-laser-diodes-by-overcoming-facet-degradation
Blue-violet emitting laser diodes tend to form SiOx deposits on the facet, causing unstable laser thresholds and beam characteristics. A suited facet coating, together with a hermetically sealed TO…
Exploration of high-temperature PECVD SiNx for strain engineering of GaN-HEMTs
/forschung/forschungsnews/exploration-of-high-temperature-pecvd-sinx-for-strain-engineering-of-gan-hemts
We demonstrate that high-temperature PECVD SiNx passivation layers enable controlled stress engineering in GaN-HEMTs. Our approach specifically shifts the threshold voltage up to 1.4 V, supporting…
