A new stripe geometry GaAlAs double heterostructure laser with built-in optical waveguide to stabilize the transverse mode parallel to the junction plane is developed. A novel optical waveguide and internal current confinement structure are realized in the structure. Lasers with strip width 4.7 ..mu..m and cavity length 200 ..mu..m showed cw threshold currents of 45--70 mA and highly stable transverse and longitudinal single-mode lasing.
