Substantially reduced threshold current density and improved efficiency in long-wavelength (> 1.4 μm) GaAs-based lasers are reported. A 20×1220 μm as-cleaved device showed a room temperature continuous-wave threshold current density of 580 A/cm2, external efficiency of 53%, and 200 mW peak output power at 1.5 μm. The pulsed threshold current density was 450 A/cm2 with 1145 mW peak output power.
