Abstract

Within the past year it has become widely apparent that practical vertical-cavity surface-emitting lasers with properties comparable to conventional inplane lasers are possible. In this paper we review recent experimental and theoretical work with single and multiple strained-layer quantum-well lasers. Device results include threshold currents as low as 0.7 mA, current densities as low as 600 A/cm², and linewidth-power products as low as 5 MHz mW.
