Data are presented on the continuous-wave (cw), room-temperature (300 K) operation of stripe-geometry In0.5(AlxGa 1-x)0.5P quantum-well heterostructure lasers defined via hydrogenation. Passivation of the Zn acceptors in the cap and upper confining layer provides gain guiding, and elimination of the current-blocking oxide reduces the thermal impedance. The resultant device is capable of better performance than conventional oxide-stripe diodes fabricated on the same material.
