Abstract

A device for emitting electromagnetic radiation includes at least one optical semiconductor element configured to generate electromagnetic radiation, at least one photodiode, and at least one beam splitter. The beam splitter is arranged relative to the optical semiconductor element and the photodiode in such a way that one portion of the electromagnetic radiation generated by the optical semiconductor element passes through the beam splitter and a further portion of the electromagnetic radiation generated by the optical semiconductor element is reflected by the beam splitter and is directed onto the photodiode.
