Abstract

A radiation-emitting semiconductor component, having a semiconductor layer sequence (1) with an active zone (2) provided for radiation generation and a first mirror arranged downstream of the active zone. The first mirror comprises a metal layer (4) and an intermediate layer (3) made of a radiation-transmissive and electrically conductive material, said intermediate layer being arranged on that side of the metal layer (4) which faces the active zone. The radiation-emitting semiconductor component is provided for operation with an optical resonator and for generating predominantly incoherent radiation as an RCLED or the radiation-emitting semiconductor component being provided for operation with an external optical resonator and for generating predominantly coherent radiation as a VECSEL.
