Results on a vertical cavity surface emitting laser with InGaAs/GaAs quantum wells and a hybrid AIAs/GaAs Bragg reflector with a metal top mirror are presented. The structure has a threshold current density of 2.1kAcm -2 and a 6% external quantum efficiency (uncorrected for substrate absorption and
