  • Abstract
    The authors report a low CW, RT threshold current (Ith) of 156-μA from a 2.8 μm diameter vertical-cavity laser (VCL) with three AlInGaAs quantum wells. Devices show no degradation after 30 h of burn-in testing at a constant current density of 22 kA/cm2 and a junction temperature of 140°C. In addition, devices were measured at various stage temperatures and it was found that the lowest Ith, 110 μA for the 2.8 μm diameter VCL, occurs near 230 K, where the quantum well gain peak and the cavity mode are aligned
