Continuous-wave lasing at room temperature in InGaSbAs/GaAlSbAs injection heterostructures emitting in the spectral range 2.2–2.4 μm

Abstract

Room-temperature cw lasing was achieved in InGaSbAs/GaAlSbAs heterostructure injection lasers emitting in the range 2.2–2.4 μm. A stripe geometry with a ridge waveguide was used. The threshold currents in the cw regime were 80–150 mA at T = 300 K.
