Abstract
In this work we report on 64 degree celsius continuous-wave operation of a 1.5 micrometer vertical cavity laser. This laser consists of two fused Al(Ga)As/GaAs mirrors with a strain-compensated InGaAsP/InP active region. Selective lateral oxidation is used for current confinement. Minimum room temperature threshold current is as low as 0.8 mA, and maximum cw output power is as high as 1 mW at 15 degrees Celsius. Pulsed operation is achieved up to 100 degrees Celsius.
