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.

Bi-directional, feed through emitter-detector for optical fiber

This invention relates to a double heterostructure diode and photodiode which is selectively switchable between an emission mode and receiving mode. A light emitting active region is localized and restricted by limitation of the area of contact to a window in a silicon dioxide layer and an optical fiber is coupled to the diode at a lateral surface to provide substantially greater light emission from the lateral surface than from side emission.
