Abstract: A semiconductor component for emitting light includes a main body that comprises at least one mesa body. The mesa body has an emission region for emitting the light. The emission region is assigned a first mirror portion, a second mirror portion, and an active portion arranged between the two mirror portions and serving to produce the light. The semiconductor component further includes electrical contacts for feeding electrical energy into the active portion, with at least one stress element that is attached to a surface of the main body. The stress element is configured to generate in the main body a material stress which has an effect on one or more polarization properties of the emitted light.

Abstract: A vertical-cavity surface-emitting laser includes a first reflector connected to a first semiconductor substrate, a second reflector, and an active region including a quantum well structure for emitting light. The active region is located in series between the first reflector and the second reflector. The first reflector is located in series between the first semiconductor substrate and the active region. A surface of an outer face of the first semiconductor substrate that faces away from the first reflector has an orientation mark that is configured so as to define a position of the vertical-cavity surface-emitting laser in a plane in parallel with the outer face of the first semiconductor substrate.
