Abstract
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 μm and cavity length 200 μm showed cw threshold currents of 45–70 mA and highly stable transverse and longitudinal single‐mode lasing.Keywords
