About the session

Electrically-pumped micro-ring lasers with azimuthal gratings were designed and fabricated using InAs/InAlGaAs/InP quantum-dot structures grown by MOCVD. Continuous-wave single-mode lasing covering 1300 nm to 1370 nm with SMSR over 40 dB was achieved. Tunable single-mode operation and on-chip integration with waveguide and SOA/photodetector are demonstrated.
