Abstract
A single-mode laser structure suitable for photonic integration is presented. The laser can be fabricated by standard photolithography without any regrowth steps. Through optimization, a threshold current as low as 13 mA and a sidemode suppression ratio (SMSR) up to 47 dB have been predicted for a 400-??m-long laser. A high yield up to 90% is also predicted with the requirement that the SMSR is higher than 40 dB at an injection current of 100 mA.
