Quantum-Well (A1)GaInP stripe lasers with lateral current and carrier confinement have been fabricated making use of the disordering of the natural superlattice at sidewalls with shallow angles during epitaxial growth on (001) GaAs substrates patterned with ridges and trenches. Excellent device quality is obtained if the substrates are patterned with ridges. With a stripe width of 5 μm required for fundamental transversal mode operation, the threshold current density of these devices is one-half that of conventional planar stripe lasers owing to improved current confinement. © 1993 IEEE
