摘要： A method and an apparatus providing an optical interconnection in an integrated circuit die. In one embodiment, an optical interconnection is used to optically interconnect a waveguide-based optical modulator through the insulating layer and back side of the semiconductor substrate of the integrated circuit die. In one embodiment, an insulating oxide layer is disposed between a semiconductor waveguide optical modulator and the back side of the semiconductor substrate. Optical conduits are disposed in the insulating oxide layer at the locations where light enters and exits the semiconductor waveguide optical modulator. In one embodiment, the optical conduits have indexes of refraction substantially equal to the indexes of refraction of the semiconductor substrate and the semiconductor waveguide optical modulator. Thus, attenuation of the light used to optically couple the semiconductor waveguide optical modulator through the back side of the semiconductor substrate is reduced.

摘要： An optical modulator that modulates light through the semiconductor substrate through the back side of a flip chip packaged integrated circuit. The optical modulator of the present invention enables integrated circuit signals to be extracted through the back side of the semiconductor substrate. In one embodiment, an optical modulator is disposed within a flip chip packaged integrated circuit die. The optical modulator includes a deflector and a diffraction grating. An infrared light beam is directed through the back side of a silicon substrate of the integrated circuit die, deflected off the deflector through the diffraction grating and back out the back side of the integrated circuit die. The diffraction grating modulates the phase of a portion of the deflected light beam in response to an integrated circuit signal. A resulting diffraction interference occurs between the phase modulated portions and nonphase modulated portions of the deflected light beam. The interference causes amplitude modulation of a zero order diffraction of the deflected light beam, from which the integrated circuit signal can be extracted. The zero order diffraction is allowed to pass through an optical passage to exit the semiconductor substrate of the flip chip packaged integrated circuit die while the non-zero order diffractions are blocked.
