Infrared and UV-C photodetectors
Making the invisible visible and using new measurement technologies
Fraunhofer IAF develops components and manufacturing processes for high-performance infrared and UV-C photodetectors.
Infrared detectors for SWIR and MWIR
- SWIR (≤ 1.7 µm) - InGaAs/InP-SPADs
- Single photon detection (e.g. for LiDAR and quantum key distribution at wavelengths around 15xx nm)
- MWIR (3–5 µm) to eSWIR (≤ 2.6 µm) - Ga-free type II superlattice
- High operating temperature (e.g. for SWAP-C-optimized, mono- and bispectral thermal imaging devices with the highest spatial resolution)
Detectors for solar-blind UV-C
- Sensitivity ≤ 280 nm with high out-of-band suppression
- Detection of very weak signals (a few tens of photons per pulse)
- Application: Gas sensor technology (e.g. molecular LiDAR for H2)
