Patent ID: 10333278

Abstract:
A semiconductor laser includes a semiconductor layer sequence having an n-conducting n-region, a p-conducting p-region and an intermediate active zone, an electrically conductive p-contact layer that impresses current directly into the p-region and is made of a transparent conductive oxide, and an electrically conductive and metallic p-contact structure located directly on the p-contact layer, wherein the semiconductor layer sequence includes two facets forming resonator end faces for the laser radiation, in at least one current-protection region directly on at least one of the facets a current impression into the p-region is suppressed, the p-contact structure terminates flush with the associated facet so that the p-contact structure does not protrude beyond the associated facet and vice versa, and the p-contact layer is removed from at least one of the current-protection regions and in this current-protection region the p-contact structure is in direct contact with the p-region over the whole area.
