Abstract

An optical bidirectional link comprising: a module having a lower surface and an upper surface. The upper surface having disposed thereon a submodule having an optical transmitter and detector mounted thereon. Circuitry mounted on the upper surface. The circuitry having electronic components for effecting bidirectional communication via the optical transmitter and detector. A cover disposed over the upper surface of the module, wherein the submodule further comprises a silicon substrate having an optical fiber disposed in v-groove, a laser, reflective surfaces, and a holographic plate disposed on an upper surface of the silicon substrate.
