Abstract:
1. An electro-optical transmitter comprising: a substrate having a generally planar configuration including an upper surface, a lower surface and an edge between the upper and the lower surfaces, and having a recess therein with a bottom surface with at least one opening therein; a multi-port lens affixed to the bottom surface of the recess; an integrated circuit affixed to the bottom surface of the recess, a plurality of light emitting devices mounted to communicate optically with the multi-port lens, each of the plurality of light emitting devices being electrically coupled to the at least one integrated circuit; a set of electrical contacts disposed on the lower surface of the substrate for connection to external circuitry, the set of electrical contacts being coupled through the substrate to the at least one integrated circuit; a plurality of optical fibers coupled through the edge of the substrate to the multi-port lens, individual ones of the optical fibers being positioned to communicate optically with individual ones of the light emitting devices; wherein electrical signals from the integrated circuit are converted to optical signals for transmission on the optical fibers, and wherein the electrical signals are provided to the lower surface of the substrate, heat is dissipated from the upper surface of the substrate, and optical signals are transmitted along the edge of the substrate.
