Lasing characteristics of MOVPE grown 1.5μΜ GalnAsP LD using directly bonded InP/Si substrate

Lasing characteristics dependent on the bonding temperature for 1.5μm GalnAsP LD grown on directly bonded InP/Si substrate was successfully obtained. We have grown laser structure by MOVPE using InP/Si substrate, and fabricated broad area edge-emitted LD. For the preparation of InP/Si substrate, the temperature during direct bonding process was changed to 350, 400, and 450 °C. The electrical and lasing characteristics dependent on the bonding temperature were compared.
