We report the fabrication and performance characteristics of (InAs1)/(GaAs)4 short-period superlattice (SPS) strained quantum-well lasers emitting near 1 μm. The SPS consists of 6 periods of 1 and 4 ML of InAs and GaAs, respectively. The 250-μm-long ridge waveguide lasers have a threshold current of 10 mA, an external differential quantum efficiency of 0.35 mW/mA facet, and have operated to a temperature of 200 °C.
