Abstract

A radiation-emitting semiconductor component includes a semiconductor body. The semiconductor body has a semiconductor layer sequence having an active region provided for generating radiation. The semiconductor component has a waveguide, which is provided for laterally guiding the radiation generated in the active region and which extends between a mirror surface and a coupling-out surface. The waveguide meets the mirror surface perpendicularly and forms an acute angle with a normal to the coupling-out surface.
