More Information
Summary:A method of manufacturing a semiconductor laser including providing a substrate having a semiconductor layer sequence with an active layer that generates light during operation of the semiconductor laser, applying a continuous contact layer having at least one first partial region and at least one second partial region on a bottom side of the substrate opposite the semiconductor layer sequence, and locally annealing the contact layer only in the at least one first partial region.
