ABSTRACT:
A method and an apparatus providing an optical input/output bus in an integrated circuit by optically routing input/output signals between integrated circuit nodes. In one embodiment, input/output signals are optically routed back and forth through the back side semiconductor substrate of a flip chip packaged integrated circuit die. An optical assembly used to generate and direct the light beams of the optical bus may be included within a heat sink thermally coupled to the back side silicon substrate of the integrated circuit die. Alternatively, the optical assembly may be embedded into the back side silicon substrate of the integrated circuit die. In operation, a light beam is directed through the back side semiconductor substrate onto an optical modulator. The optical modulator modulates and deflects the light beam. The deflected light beam is routed to a deflector that directs the modulated and deflected light beam through the back side semiconductor substrate onto an optical demodulator.
