A method of manufacturing an optoelectronic component includes providing a carrier with an upper side; arranging an optoelectronic semiconductor chip above the upper side of the carrier; arranging a casting material over the upper side of the carrier, wherein the optoelectronic semiconductor chip is embedded in the casting material, and the casting material forms a cast surface; and removing a portion of the casting material at the cast surface, wherein a topography is generated at the cast surface, and the removal of a portion of the casting material at the cast surface takes place through laser interference structuring.

Method of producing an optoelectronic component

An optoelectronic semiconductor component includes a semiconductor layer sequence that generates radiation, the semiconductor layer sequence has an emission side and a rear side opposite said emission side, a mirror for the generated radiation on the rear side, a carrier that is transmissive to the radiation generated, on the emission side, and a reflector housing on side surfaces of the carrier, the reflector housing is impermeable to the generated radiation and configured for diffuse reflection of generated radiation and includes a radiation exit opening, wherein at least one of a width of an opening in the reflector housing and an area of the radiation exit opening decrease(s) in a direction away from the emission side, and a maximum emission of the generated radiation takes place in an emission angle range of 30&#xb0; to 60&#xb0;, relative to a perpendicular to the emission side.

Optoelectronic semiconductor component

A radiation-emitting component is disclosed. Embodiments of the invention relate to a radiation-emitting component with an organic layer stack which is arranged on a substrate. An outcoupling structure is arranged on a substrate face facing the organic layer stack, an additional optical layer is arranged between the substrate and the outcoupling structure, and the additional optical structure has a refractive index which is lower than the refractive index of the substrate, or the additional optical layer forms a mirror which has a selective angle and which only allows light that can be coupled out of the substrate at a substrate boundary surface facing away from the organic layer sequence to pass, the light being generated in the organic layer stack during operation.

Device for generating polarized electromagnetic radiation has a diffuser and a polarizer. The diffuser is arranged in a beam path of the electromagnetic radiation. The polarizer is arranged in the beam path of the electromagnetic radiation, to be precise downstream of the diffuser in the direction of propagation of the electromagnetic radiation. The polarizer has a reflective side facing the diffuser, said reflective side being at least partly reflective to the electromagnetic radiation. The polarizer transmits electromagnetic radiation having a predefined polarization and reflects electromagnetic radiation not having the predefined polarization back to the diffuser. The diffuser scatters, in a non-polarization-maintaining manner, at least one portion of the reflected-back electromagnetic radiation not having the predefined polarization.
