An optoelectronic component is specified comprising a semiconductor body comprising a first semiconductor layer sequence and a second semiconductor layer sequence which are arranged on top of one another in a stacking direction, wherein the first semiconductor layer sequence has a first active region, which generates electromagnetic primary radiation with a first peak wavelength the second semiconductor layer sequence comprises a second active region, which has a section configured to partially absorb electromagnetic primary radiation and to re-emit electromagnetic secondary radiation having a second peak wavelength, and the first peak wavelength is in a red wavelength range and the second peak wavelength is in an infrared wavelength range, or the first peak wavelength is smaller than the second peak wavelength by at most 100 nanometers.

Optoelectronic component, method for driving an optoelectronic component, and illumination device

Provided is an optoelectronic semiconductor chip including a semiconductor layer sequence in which an active zone for generating radiation is located between a first semiconductor region and a second semiconductor region. A first electrical contact of the semiconductor layer sequence is applied to the first semiconductor region. A second electrical contact is applied to the second semiconductor region. The second electrical contact is located in a trench of the second semiconductor region. The trench is restricted to the second semiconductor region and ends at a distance from the active zone. A distance between a bottom of the trench and the active zone is at most 3 &#x3bc;m.
