Abstract

An optocoupler has an organic light emitter and an inorganic photodetector with a detector area, the detector area being optically coupled to the organic light emitter. The organic light emitter converts an electrical input signal into a light signal and the inorganic photodetector converts the light signal into an electrical output signal, the organic light emitter and the inorganic photodetector being integrated in a component and galvanically separated.
