The performance of strained layer InGaAs/GaAs vertical cavity surface emitting lasers defined by ion implantation over a approximately 75 degrees C temperature range is reported on. Maximum CW output levels for the temperature extremes of 10 and 86 degrees C are 7.5 MW and 200 mu W, respectively for 20*20 mu m2 devices. The temperature dependence of the CW threshold current exhibits exponential behaviour to 80 degrees C.
