Abstract :
We present results from reliability studies on hybrid silicon distributed feedback lasers. The devices show no degradation at 70 °C for 5000 h. We investigate the influence on reliability of a superlattice between the active region and the bonded interface. Transmission electron microscopy images from a failed device show no defects in the active region along a 15-μm-long longitudinal cross section at the center of the laser cavity.
