Abstract

A reflex coupler has an organic light emitter for generating a light signal and an inorganic photodetector with a detector area. The organic light emitter and the detector area are optically coupled as a result of radiation returned from an object onto which the light signal impinges, and the organic light emitter and the inorganic photodetector are integrated in one device.
