Abstract:
A radiation-emitting component includes a semiconductor layer stack having an active region that emits electromagnetic radiation, and at least one surface of the semiconductor layer stack or of an optical element that transmits the electromagnetic radiation wherein the surface has a normal vector, wherein on the at least one surface of the semiconductor layer stack or of the optical element through which the electromagnetic radiation passes, an antireflection layer is arranged such that, for a predetermined wavelength, it has a minimum reflection at a viewing angle relative to the normal vector of the surface at which an increase in a zonal luminous flux of the electromagnetic radiation has approximately a maximum.
