Long-wavelength InGaAsP/InP vertical-cavity surface-emitting lasers (VCSEL’s) are promising for optical communication systems. However, room-temperature continuous-wave (cw) operation has not yet been achieved because of the high temperature dependence of the Auger recombination, the low thermal conductivity of the materials, insufficient mirror reflectivity, and device structures with poor heat-dissipation capabilities. Therefore design optimization considering thermal-resistance and size-dependent cavity loss is very important.
