Abstract:
The invention relates to a semiconductor laser with a semiconductor body (1) that comprises a first and a second main surface, preferably provided with one contact surface (2,3) each, and a first and a second mirror surface (6,7). An active layer (4) and a current-carrying layer (5) are interposed between the main surfaces. The current carrying layer (5) has at least one strip-shaped resistance zone (8) that runs at an angle to the resonator axis (18) and whose specific surface resistance is higher in at least some zones than in the zones of the current carrying layer (5) adjoining the resistance zone (8).
Abstract:
A radiation-emitting semiconductor body with a carrier substrate. A structured connection is produced between a semiconductor layer sequence (2) and a carrier substrate wafer (1). The semiconductor layer sequence is subdivided into a plurality of semiconductor layer stacks (200) by means of cuts (6) through the semiconductor layer sequence, and the carrier substrate wafer (1) is subdivided into a plurality of carrier substrates (100) by means of cuts (7) through the carrier substrate wafer (1). In the method, the structured connection is formed in such a way that at least one semiconductor layer stack (200) is connected to one and only one associated carrier substrate (100). In addition, at least one cut (7) through the carrier substrate wafer is not extended by any of the cuts (6) through the semiconductor layer sequence such that a straight cut results through the carrier substrate wafer and the semiconductor layer sequence.
Abstract:
A semiconductor laser has a semiconductor body with first and second main areas, preferably each provided with a contact area, and also first and second mirror areas. An active layer and a current-carrying layer are formed between the main areas. The current-carrying layer has at least one strip-type resistance region, which runs transversely with respect to the resonator axis and whose sheet resistivity is increased at least in partial regions compared with the regions of the current-carrying layer that adjoin the resistance region.
