Abstract :
Low-threshold room-temperature pulsed operation of InGaAs-InGaAsP multiquantum-well (MQW) lasers (λ≃1.55 μm) on Si substrates is demonstrated. These laser structures were first grown on InP substrates, then bonded at 700°C onto Si substrates with buffer layers. The mesa-stripe broad-area lasers have a threshold current density of 1.7 kA/cm2 (50 μm mesa width, 330 μm cavity length), which is comparable to the value for lasers on InP substrates
