Department of Photonics conducts scientific research on innovative light sources and detectors applied in the field of medicine, environmental protection, industry and military. A considerable part of our activity is focused on semiconductor devices operating within near- and mid-infrared spectral range.
The research realized in the department involves, in particular:
- unipolar quantum-cascade lasers (QCLs) based on AIII — BV structures
- high power disc lasers; optically pumped external-cavity lasers (VECSELs)
- antimonide-based type II superlattice photodetectors
Our R&D staff employs a wide range of advanced material characterisation techniques and methods of design, fabrication and testing of semiconductor devices. The department has two Molecular Beam Epitaxy (MBE) reactors and a fully equipped processing line for device assembly and packaging. Our research facilities allows for controlling and optimization of each step of the device fabrication. Thanks to such a comprehensive approach we are able to develop cutting-edge semiconductor devices of outstanding performance and reliability.
