Abstract
An optoelectronic device comprises a light emitting element having a source from which a light signal is emitted, a semiconductor body having a light receiving element, a control circuit for the emitting element, and a circuit for the receiving element which are integrated in the semiconductor body. The light emitting element is electrically connected to the control circuit and optically coupled to the receiving element through a transparent medium for the light signal. The optoelectronic device has an increased integration density and photocoupling efficiency.
