摘　　要：InCaAsSb/AlGaAsSb multi quantum well ridge waveguide lasers at 2.1 μm wavelength are fabricated by using molecular beam epitaxy. Continuous wave performance and tunability of the lasers are evaluated in a wide temperature range extend to 80℃. Output power of the laser at 30℃ exceeds 30 m W/facet at driving current of 0.5 A, the characteristic temperature To is 89K in 0-50℃ range. No fast degradation is observed in accelerated aging test at 90℃ for those lasers with lower Al content in cladding layers. Temperature tunability of the lasers is 1.36 nm/K. Single-mode output with side mode suppression ratios greater than 20 dB is achieved in a certain driving current region; current tunability is 8 × 10^-3 nm/mA regardless of mode hopping.InCaAsSb/AlGaAsSb multi quantum well ridge waveguide lasers at 2.1 μm wavelength are fabricated by using molecular beam epitaxy.
