Abstract :
Separate confinement single-quantum-well lasers with 100-120 Å-thick strained Ga1-xInxAs/GaAs active layers have been grown on (100) GaAs substrates by metalorganic chemical vapour deposition. Ten-stripe proton-implanted arrays with 90 μm-wide aperture and 250 μm cavity length emit 200 mW CW optical power at wavelengths 0.87⩽λ⩽0.95 μm. Lifetest data on an uncoated device emitting 90 mW/facet at 50°C and λ=0.95 μm suggest a mean-time-to-failure in excess of 2500 h at room temperature. The performance of lasers with strained Ga1-xInxAs quantum wells is comparable to that of unstrained AlxGa1-xAs/GaAs quantum-well lasers without facet coating
