Abstract :
Injection locking and switching characteristics are investigated in the novel retro-reflector-cavitiy-based semiconductor ring laser with equivalent circular radius of 26 mum. The allowed detuning range is up to ~3 GHz wide and the highest side mode suppression ratio of ~43.7 dB can be achieved. A fast response speed of ~70 ps to the cavity is achieved, which indicates that this device can be utilized as an all optical switch at a data rate of 10 Gb/s or higher.
