InGaAs/GaAs vertical-cavity surface-emitting laserson (311)B GaAs substrate

Abstract
InGaAs/GaAs vertical cavity top-emitting dielectric-mirror surface-emitting lasers have been fabricated on a (311)B GaAs substrate. The threshold current was 25 mA at a lasing wavelength of 0.97 µm under pulsed operation at room temperature. The output was linearly polarised in the [2̄33] direction.
