A recently installed DRIE tool enables flexible through silicon substrate etching, needed to form, e.g., through silicon vias used to integrate InP-based devices with silicon and to fabricate micro gas cells.

In a joint project with PTB, we are developing a compact atomic magnetometer, which uses frequency-stabilized lasers and vaporized cesium atoms.

Scientists at FBH investigated the wavelength tuning behavior in high-power distributed feedback (DFB) lasers. The results reveal insight to the mechanisms leading to mode hops in those lasers and the conditions for devices with a large continuous wavelength tuning range.

Dr. Sven Einfeldt & Dr. Neysha Lobo Ploch explain how our UVC LEDs can be used for disinfection in medicine, what the challenges are and how we are currently developing our systems.

The current frequent issue focuses on our developments in the field of high-power diode lasers and their applications.
