Abstract

An optoelectronic component includes an active zone that generates electromagnetic radiation, wherein the electromagnetic radiation is guided in a guide plane, the electromagnetic radiation is output essentially in the guide plane, the active zone emits stray radiation laterally with respect to the guide plane, an electrical contact pad is provided, the contact pad is arranged outside the guide plane, the contact pad is formed by a surface at least partially covered by a conductive layer, the surface has inclined partial faces, and the electrically conductive layer on at least a subset of the inclined faces of the contact pad is configured to be so thin that electromagnetic stray radiation is emitted via the subset of the inclined faces.
