Abstract

A radiation-emitting semiconductor chip includes a substrate; an epitaxial semiconductor layer sequence having an active zone that generates electromagnetic radiation of a first wavelength range, wherein the substrate is transparent to electromagnetic radiation of the active zone; and an optically active layer arranged on a side surface of the substrate and on a rear main surface of the semiconductor chip, which lies opposite to a radiation exit surface of the semiconductor chip.
