In the field of optoelectronics, we mainly develop photodetectors and semiconductor lasers for the infrared spectral range (wavelength > 1,5 µm), but also for the solar-blind ultraviolet spectral range ( < 280 nm).
- We customize our lasers for the emission range of 2 – 11 µm, particularly focussing on quantum cascade lasers and optically pumped semiconductor disk lasers.
- With regard to infrared photodetectors our focus lies on matrix and single detectors of highest performance based on antimonic typ II superlattices and InGaAs. We develop highly sensitive avalanche photodiodes (APDs) with integrated signal amplification for the detection of very weak optical signals. Our bispectral detectors allow for color vision in the infrared regime.
