Abstract

An optoelectronic component for mixing electromagnetic radiation having different wavelengths, for example, for the far field is disclosed. In an embodiment the optoelectronic component includes a carrier, at least one first semiconductor chip arranged on the carrier and having a first radiation exit surface for emitting electromagnetic radiation in a first spectral range and at least one second semiconductor chip arranged on the carrier and having a second radiation exit surface for emitting electromagnetic radiation in a second spectral range, wherein a diffusing layer is arranged on the first and second radiation exit surfaces of the semiconductor chips that face away from the carrier and wherein a reflecting layer is arranged between the first semiconductor chip and the second semiconductor chip, the first and second radiation exit surfaces being free from the reflecting layer at least in regions.
