Room-temperature continuous-wave operation VCSEL at 1.48 /spl mu/m with Sb-based Bragg reflector

The authors present, for the first time, room temperature CW operation of an optically-pumped vertical cavity laser emitting at 1.48 /spl mu/m, incorporating an Sb-based mirror on InP. The structure also includes strained AlGaInAs quantum wells and a wafer-fused AlGaAs mirror. The input threshold power is 50 mW at 20/spl deg/C and has a minimum value of 27 mW at 230 K.
