Strained-layer GRINSCH-SQW InGaAs lasers operating CW at 1.01 μm have been CW life tested to over 20 000 h while exhibiting an average degradation rate of 1.3% per kh. These uncoated lasers were life tested at 70 mW (per facet) in constant power mode at a heatsink temperature of 30°C. In addition to their longevity, these lasers exhibited a resistance to sudden failure with an unscreened sample of fifteen lasers experiencing total survival to 10 000 h.
