Direct-current-pumped Fabry-Perot lasing was observed from a Si/III-V hybrid laser fabricated by the Ar/O2 plasma assisted direct bonding of an InP-based III-V active layer on a highly doped silicon micro rib. Electrical pumping from a silicon micro rib to InGaAsP multiple quantum wells (MQWs) for generating CW Fabry-Perot lasing was successfully demonstrated at a threshold current of 65 mA at 5 °C. The semiconductive and optical properties of the hetero-junction between the silicon micro rib and InGaAsP MQWs under direct current injection were measured and discussed.
