Abstract
An optoelectronic semiconductor chip including a semiconductor body of semiconductor material, an outcoupling face arranged downstream of the semiconductor body in an emission direction and a mirror layer, wherein the semiconductor body includes an active layer that generates radiation, the mirror layer is arranged on the side of the semiconductor body remote from the outcoupling face, and a gap between the active layer and the mirror layer is set such that radiation emitted by the active layer towards the outcoupling face interferes with radiation reflected at the mirror layer such that the semiconductor chip features an emitted radiation pattern with a selected direction in the forward direction.
