Abstract

Device and tuning characteristics of a novel heterogeneously integrated III-V-on-silicon three-section distributed Bragg reflector laser are presented. The laser exhibits a continuous wavelength tuning range of more than 12 nm. Thermal tuning is achieved through carrier injection in the passive tuning layer of a III-V tunable twin-guide membrane. Single-mode lasing with a sidemode suppression ratio larger than 30 dB over the entire tuning range is realised through implementation of a sidewall-corrugated silicon-on-insulator waveguide grating as one of the laser mirrors.
