Abstract
An electro-optical communication device which includes a light transmissive conduit integrally formed to interconnect a light emitter and a light detector. The length over which the light transmissive conduit extends is substantially greater than the size of either the light emitter or the light detector. In the preferred embodiment, the light emitter and the light detector are each formed from amorphous semiconductor alloy material and may be substantially surrounded by the light transmissive conduit.
