A laser operating at low threshold current is indispensable for the construction of superparallel optical interconnections. Initially we examine the current threshold characteristics of surface emitting InGaAs/GaAs lasers, and demonstrate the possibility for working with a threshold current below 10

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
