Abstract

A radiation-emitting component (10) having a layer stack (1) which is based on a semiconductor material and which has an active layer sequence (4) for generating electromagnetic radiation, and a filter element (2) which is arranged after the active layer sequence (4) in the irradiation direction (A) and by means of which a first radiation component is transmitted, and a second radiation component is reflected into the layer stack (1), wherein the second radiation component is subjected to a deflection process or an absorption and emission process, and the deflected or emitted radiation impinges on the filter element (2).
