| Abstract: | We report the high performance and high reliability of the 1.55 μm current-blocking grating complex-coupled InGaAsP strained distributed-feedback MQW lasers. Small variation in slope efficiency, high characteristic temperature, and high side mode suppression ratio have been achieved over a wide temperature range of 20°C-90°C. From the accelerated aging test, the median life at 25°C and 5 mW is estimated to be longer than 50 years |
