Abstract
A CW operation temperature of 160°C is demonstrated in InGaAs/GaAs double quantum well vertical cavity surface emitting lasers (VCSELs). The effect of offset-gain is considered in the design, and wet chemical etching is employed for forming the mesa structure to reduce surface recombination. A low threshold current of 5.2 mA is achieved at 160°C
