Abstract:
An edge-emitting semiconductor laser and a method for operating a semiconductor laser are disclosed. The edge-emitting semiconductor laser includes an active zone within a semiconductor layer sequence and a stress layer. The active zone is configured for being energized only in a longitudinal strip perpendicular to a growth direction of the semiconductor layer sequence. The semiconductor layer sequence has a constant thickness throughout in the region of the longitudinal strip so that the semiconductor laser is gain-guided. The stress layer may locally stress the semiconductor layer sequence in a direction perpendicular to the longitudinal strip and in a direction perpendicular to the growth direction. A refractive index of the semiconductor layer sequence, in regions which, seen in plan view, are located next to the longitudinal strip, for the laser radiation generated during operation is reduced by at least 2×10 −4  and by at most 5×10 −3 .

Claim (Index 2):
The semiconductor laser according to  claim 1 , wherein tensile stress induced by the stress layer is at least 50 MPa and at most 0.5 GPa, and wherein a spacing between the stress layer and the active zone in a direction longitudinally of the growth direction is at least 0.1 \u03bcm and at most 3 \u03bcm.
