Abstract :
A buried ridge stripe (BRS) structure InGaAsP-Si hybrid laser based on selective area metal bonding (SAMB) method is demonstrated. This novel hybrid laser structure combines the SAMB method´s advantage of low bonding requirements and great flexibility and the BRS lasers´ low threshold, high thermal performance, and good optical field and carrier confinement. The 300-$mu $ m-long hybrid laser has a threshold current of 14 mA and a maximum single-facet output power of 5.4 mW at room temperature, with a slope efficiency of 0.17 W/A. The laser has a characteristic temperature of 50 K, with continuous wave operation at temperature >50 °C.
