Abstract
An edge emitting semiconductor laser includes a semiconductor body including a waveguide region, wherein the waveguide region includes a first waveguide layer, a second waveguide layer and an active layer arranged between the first and second waveguide layers and generates laser radiation, the waveguide region is arranged between first and second cladding layers disposed downstream of the waveguide region in a growth direction of the semiconductor body, a phase structure is formed in the semiconductor body and includes at least one cutout extending from a top side of the semiconductor body into the second cladding layer, at least one first intermediate layer including a semiconductor material different from the semiconductor material of the second cladding layer is embedded into the second cladding layer, and the cutout extends from a top side of the semiconductor body at least partly into the first intermediate layer.
