Abstract

Various embodiments may relate to an optoelectronic component, including an optoelectronic structure, which is designed to provide a first electromagnetic radiation, and a measuring structure, which is designed to measure electromagnetic radiation, wherein the measuring structure has an optically active structure and at least one electro-optical structure. The optically active structure is optically coupled to the optoelectronic structure. The optically active structure is designed to absorb an electromagnetic radiation in such a way that the optically active structure produces a measured signal from the absorbed electromagnetic radiation. The absorbed electromagnetic radiation at least partially includes the first electromagnetic radiation and/or at least one second electromagnetic radiation of an external radiation source. The electro-optical structure is designed in such a way that the electro-optical structure has an adjustable transmittance, such that the fraction of the second electromagnetic radiation incident on the optically active structure can be adjusted.
