Patent ID: 8831061

Claim:
An edge emitting semiconductor laser chip comprising: a semiconductor body that comprises at least one active zone in which electromagnetic radiation is generated during operation of the semiconductor laser chip; at least one contact strip arranged on a top surface at a top side of the semiconductor body; and at least two delimiting structures for delimiting current spreading between the contact strip and the active zone, wherein the delimiting structures are arranged on both sides of the contact strip, wherein the delimiting structures are arranged with a filling factor of at least 10% and at most 90% on both sides of the contact strip, wherein at least one delimiting structure comprises a cutout in the semiconductor body, wherein the cutout comprises a filling line in a direction parallel to the contact strip, wherein the cutout is free of a filling material on a side close to the contact strip, and wherein the cutout is filled with the filling material on a side away from the contact strip.
