Abstract
An optoelectronic component includes a boundary layer is arranged between a semiconductor body and a metallic layer in a lateral direction, adjoins the semiconductor body at least in places, covers an active layer laterally, and has a lower refractive index compared to the semiconductor body, a metallic layer is configured to prevent the electromagnetic radiation generated during operation of the component and passes through the boundary layer from impinging on a mold body, the boundary layer is formed from a radiation-transmitting dielectric material having a refractive index of 1 to 2, and a layer thickness of the boundary layer is at least 400 nm and selected such that an amplitude of an evanescent wave, which is obtained in the event of total internal reflection at an interface between the boundary layer and the semiconductor body, is reduced to less than 37% of its original value within the boundary layer.
