Jörgen Bengtsson

Docent at Chalmers, Microtechnology and Nanoscience (MC2), Photonics

Jörgen Bengtsson supervises Photonics Laboratory´s efforts on novel feedback mechanisms and elements in semiconductor microlasers. As an Associate Professor he shares his work mainly between the High-speed microlaser group and the Nitride optical devices group, together with his Ph.D. students focusing his research on superfast wavelength-controllable energy-efficient lasers for communication, and microlasers for new wavelengths in the ultraviolet-blue-green wavelength range for biomedical applications. He also develops and lectures the popular hands-on course in Numerical photonics.
