Low-threshold room temperature continuous wave 1.49 μm GaInNAsSb lasers were studied. Room temperature threshold current density of 1.1 kA/cm 2 was observed with a high external quantum efficiency of 40% and maximum output power of 30 mW from both facets. The results showed a record high external efficiency of 0.34 W/A.
