The single mode laser structure based on etched slots suitable for photonic integration is presented in this paper. The laser is made completely dependent on a group of slots on one side of the laser cavity. The fabricated 750 μm long single section laser exhibits a threshold current and a slope efficiency of about 32 mA and 0.11 mW/mA, respectively. The stable single mode operation has been observed...
A high-yield two-section single-mode laser based on a 37th-order surface-grating is presented. By tuning the back section current, the laser exhibits a side-mode-suppression-ratio of upto 47dB over a temperature range from 15°C to 65°C.
A single-mode laser structure based on slots suitable for monolithic photonic integration is presented. The laser can be fabricated by photolithography without any regrowth steps. Stable single-mode performance with a sidemode suppression ratio up to 50 dB at twice threshold has been demonstrated for the fabricated lasers.
A single-mode laser structure suitable for monolithic photonic integration is presented. A low threshold, and a sidemode suppression ratio (SMSR) up to 52 dB have been predicted and realised for a 400 μm-long laser.
