Abstract: In one embodiment, the optoelectronic component comprises a first emission zone, which emits electromagnetic radiation during operation. Furthermore, the component comprises an optical waveguide with an entrance side facing the first emission zone, a distribution element and with output coupling structures on a side of the distribution element facing away from the first emission zone. The optical waveguide is a simply connected solid body. In a top view of the side of the optical waveguide facing away from the first emission zone, the distribution element completely covers the first emission zone. The output coupling structures are individual, spaced-apart elevations, each of which extends away from the distribution element and comprises an output coupling surface at an end facing away from the distribution element. A structure that is nontransmissive to the radiation of the first emission zone is arranged on the optical waveguide in the region between the output coupling structures.

Abstract: An optoelectronic semiconductor component is specified having a semiconductor body comprising an active region provided for generating electromagnetic radiation, wherein the semiconductor body comprises a main surface which runs parallel to a main extension plane of the semiconductor body. Furthermore, the optoelectronic semiconductor component comprises a contact region, which is arranged on a side of the main surface facing away from the active region and is provided for making electrical contact with the semiconductor body, and a reflection layer, which is arranged on the side of the main surface facing away from the active region and reflects the electromagnetic radiation generated in the active region at least partially back in the direction of the active region. Further, a part of the main surface forms a radiation output coupling surface which is at least partially laterally limited by the reflection layer.
