ABSTRACT:
An optical function semiconductor device formed by opto-electrical loop coupling of a light emitting diode and a photodetector, the latter of which receives a part of an output light of the former controlled by an output current thereof, can be readily miniaturized and integrated as a fundamental function active device self-containing a light source and presenting various useful novel functions of the optoelectronic technology between the external input and the output lights.
