Abstract
A buried heterostructure laser which obtains lowest mode operation by larger differences in loss between the lowest and higher order modes is described. The loss is achieved by interface scattering between the mesa and the burying layer. The scattering losses increase with refractive index discontinuity, interface roughness and decreasing mesa width. Stabilization results because scattering losses increase rapidly with the order of the transverse modes.
