Abstract:
A semiconductor laser includes a semiconductor layer sequence, an active zone, a ridge waveguide as an elevation of a top side of the semiconductor layer sequence, the longitudinal axis of which is oriented along the active zone, a contact metalization, and a current flow layer in direct contact with the contact metalization, wherein the top side of the semiconductor layer sequence includes a section adjoining one of the two facets over the width of the section relative to a longitudinal axis of the ridge waveguide, the section includes a subsection of the top side of the ridge waveguide, the subsection adjoins one of two facets over a width of the ridge waveguide relative to the longitudinal axis of the ridge waveguide, the section is partly delimited by a plurality of current flow layer sections of the current flow layer, and the section is free of the current flow layer.

Claim (Index 23):
A method of producing a semiconductor laser comprising:\n providing a semiconductor layer sequence comprising an active zone, wherein the semiconductor layer sequence comprises a ridge waveguide configured from the semiconductor layer sequence as an elevation of a top side of the semiconductor layer sequence, said elevation lying above the active zone, and the longitudinal axis of which is oriented along the active zone, wherein a contact metalization is applied on a top side of the ridge waveguide facing away from the active zone, defining two breaking lines extending transversely with respect to the longitudinal axis of the ridge waveguide and parallel to the top side of the semiconductor layer sequence, applying a current flow layer on the semiconductor layer sequence such that, after the applying, the current flow layer is in direct contact with the contact metalization, wherein the top side of the semiconductor layer sequence comprises a section adjoining one of the two breaking lines over the width of said section relative to a longitudinal axis of the ridge waveguide, the section comprises at least one subsection of the top side of the ridge waveguide, the subsection extends in a manner adjoining said one of the two breaking lines over a width of the ridge waveguide relative to the longitudinal axis of the ridge waveguide, the section is partly delimited by a plurality of current flow layer sections of the current flow layer, and the section is free of the current flow layer, and breaking the semiconductor layer sequence along the two breaking lines such that two opposite facets defining a resonator are formed along the two breaking lines, wherein the active zone is configured between the two facets.
