Double-fused 1.5 /spl mu/m vertical cavity lasers with record high T/sub o/ of 132 K at room temperature [Al(Ga)As/GaAs]

摘要

The authors report record high temperature performance of a novel long wavelength vertical cavity laser using an electron barrier, operating continuous-wave up to 71/spl deg/C. A record high characteristic temperature (T/sub o/) of 132 K has been measured over an operating range of -75 to 35/spl deg/C.
