Abstract

Abstract: A single mode laser based on novel deep etched V-notch reflectors is presented in this paper. The reported device has a stable single mode operation and a side mode suppression ratio of 37 dB. The laser is widely tunable and it can be fine-tuned. Moreover, the laser cavity is monolithically integrated with an active multimode interference reflector, and has a total length of860 μ m .
