ABSTRACT:
A unitary emitter-detector diode device for direct optical coupling to optical transmission lines as two surface oriental optical fibers on lateral surfaces of the device. The device has a p-n junction formed between a heavily doped semiconducting layer and a lightly doped semiconducting layer and means for guiding and concentrating the recombination of carriers within the diode. The feed through geometry permits transmitting in either direction from the device as well as detecting.
