Very low threshold buried heterostructure quantum well lasers by laser-assisted disordering

Abstract
Data are presented on high-quality buried heterostructure lasers fabricated by laser-assisted disordering of GaAs-AlGaAs quantum well heterostructures. The typical cw threshold current is 4 mA and the maximum power output is 27 mW. The devices exhibit single fundamental mode operation with 34 dB attenuation of longitudinal side modes.
