Abstract :
A 1.9 μm hybrid silicon/III-V laser based on a wafer bonding technique is reported. The gain materials are InGaAs multiple quantum wells grown on InP substrate, with strain compensation between barriers and wells. The III-V wafer is bonded to a silicon-on-insulator wafer with processed silicon waveguides and transition tapers. Laser emission with a threshold current of 95 mA at room temperature and 45 mA at 5 °C is demonstrated.
