Abstract:A wide variety of III-V on silicon devices have been demonstrated using direct bonding to achieve high performance, high yield and excellent lifetimes. Examples include a 2.54 Tbit/s network on chip, fully integrated optical gyroscopes and 100 Gbit/s optical transceivers. A related approach is to epitaxially grow III-V quantum dot lasers on silicon. This approach has made excellent progress, with submilliamp laser thresholds demonstrated. Recent advances include growth on on-axis (001) Si, threading dislocation density reduction, and improvement in laser lifetimes.
