Abstract

A radiation-emitting component includes a semiconductor chip which has a first main surface, a second main surface on an opposite side from the first main surface and an active region that generates radiation; a carrier on which the semiconductor chip is fixed on the side of the second main surface; an output layer arranged on the first main surface of the semiconductor chip and forming a lateral output surface spaced apart from the semiconductor chip in a lateral direction, a recess tapering in a direction of the semiconductor chip being, formed in the output layer and deflecting radiation emerging from the first main surface during operation into the direction of the lateral output surface.
