Room-temperature pulsed operation of 1.5-μm vertical cavity lasers with an InP-based Bragg reflector

We report on a 1.5-μm vertical-cavity laser that utilizes one GaInAsP-InP and one Si-SiO
₂
mirror in combination with a strain-compensated GaInAsP quantum-well active layer. Pulsed lasing operation was achieved in a temperature range from -160 to +43/spl deg/C. The lasers exhibit 30-mA pulsed threshold current at room temperature. CW operation was obtained up to -25/spl deg/C.
