The lasing performance of deeply etched distributed Bragg reflector (DBR) lasers was improved to a threshold current as low as 7.2 mA and a differential quantum efficiency as high as 50% with high uniformity. The reflectivity of the 15-DBR reflector was estimated to be as high as 95% from the threshold current dependence on the active region length. A preliminary test under room-temperature CW operation showed stable operation for a duration in excess of 4000 hours. |
