Abstract:
1. An edge emitting semiconductor laser comprising: a semiconductor body, which has a waveguide region; wherein the waveguide region has a first waveguide layer, a second waveguide layer and an active layer for generating laser radiation, the active layer being arranged between the first waveguide layer and the second waveguide layer; wherein the waveguide region is arranged between a first cladding layer and a second cladding layer, which is disposed downstream of the waveguide region in a growth direction of the semiconductor body; wherein the semiconductor body has a main region and at least one phase structure region that is adjacent to the main region in a lateral direction and in which is formed a phase structure for the selection of lateral modes of the laser radiation emitted by the active layer; and wherein the phase structure region is formed outside the waveguide region.
