Research output: Contribution to conferencePaperpeer-review


Long-wavelength InP-based vertical cavity surface emitting laser was presented. The device structure was based on buried tunnel junction concept and yielded small Joule heating and sufficient heatsinking capabilities. Joule heating was reduced by the application of a low-resistance tunnel junction which was laterally structured and subsequently regrown to provide a self-aligned electrical and optical confinement. Results demonstrated that for small apertures a sufficient output power of around 0.5 mW could be maintained at high operating temperatures around 80°C.
