Keywords:semiconductor laser, distributed-reflector laser, membrane structure

The temperature dependences of membrane distributed-reflector laser on a Si substrate which showed low threshold current (0.29 mA) and relatively high differential quantum efficiency (23% from the front side) at 20 °C were measured. The sub-mA threshold current operation up to 90 °C was obtained under a continuous-wave condition. Further, single mode operation up to 80 °C was also obtained.
