    摘要: An optoelectronic component (1) is specified, comprising a semiconductor body (2) with a semiconductor layer sequence. The semiconductor layer sequence of the semiconductor body (2) comprises a pump region (3) provided for generating a pump radiation and an emission region (4) provided for generating an emission radiation. The emission region (4) and the pump region (3) are arranged one above the other. The pump radiation optically pumps the emission region (4) during operation of the optoelectronic component (1). The emission radiation emerges from the semiconductor body (2) with the semiconductor layer sequence in a lateral direction during operation of the optoelectronic component (1).

    摘要: An optoelectronic semiconductor chip, the latter includes a carrier and a semiconductor layer sequence grown on the carrier. The semiconductor layer sequence is based on a nitride-compound semiconductor material and contains at least one active zone for generating electromagnetic radiation and at least one waveguide layer, which indirectly or directly adjoins the active zone. A waveguide being formed. In addition, the semiconductor layer sequence includes a p-cladding layer adjoining the waveguide layer on a p-doped side and/or an n-cladding layer on an n-doped side of the active zone. The waveguide layer indirectly or directly adjoins the cladding layer. An effective refractive index of a mode guided in the waveguide is in this case greater than a refractive index of the carrier.
