    摘要: An optical modulator that modulates light through the semiconductor substrate through the back side of a flip chip packaged integrated circuit. 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. A first infrared optical beam having a photon energy less than the band gap energy of the semiconductor substrate is directed through the back side of the semiconductor 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. A second infrared optical beam having a photon energy greater than or equal to the band gap energy of the semiconductor substrate is directed through the back side of the semiconductor substrate to generate free charge carriers and increase the modulation depth of the optical modulator. The diffraction grating modulates the phase of a portion of the deflected optical beam in response to an integrated circuit signal. A resulting diffraction interference occurs between the phase modulated portions and non-phase modulated portions of the deflected optical beam. The interference causes amplitude modulation of the zeroth order diffraction or higher order diffractions of the deflected first optical beam, from which the integrated circuit signal can be extracted.

    摘要: A method and an apparatus for cooling a semiconductor die. In one embodiment, a C4 packaged semiconductor die is thermally coupled to a cooling plate having an opening. The opening of the cooling plate is disposed over a back side surface of the semiconductor die such that direct unobstructed access to the exposed back side surface of the semiconductor die is provided. A conformable thermal conductor, such as indium, is disposed between the semiconductor die and the cooling plate to improve the thermal coupling between the semiconductor and cooling plate. In one embodiment, the semiconductor die is mounted on a circuit board and a cooling block is disposed on the opposite side of the circuit board. The cooling plate is thermally coupled to the cooling block with heat transfer conduits, such as thermal screws, that extend through the circuit board to transfer the heat from the semiconductor die through the cooling plate through the heat transfer conduits to the cooling block located on the opposite side of the circuit board. In one embodiment, coolant is circulated through the cooling block to remove heat from the cooling block.

    摘要: A semiconductor-based Raman ring amplifier is disclosed. A method according to aspects of the present invention includes directing a pump optical beam having a pump wavelength and an input pump power level from an optical waveguide into a ring resonator. The optical waveguide and ring resonator are comprised in semiconductor material. A signal optical beam having a signal encoded thereon at a signal wavelength is directed from the optical waveguide into the ring resonator. The pump optical beam is resonated within the ring resonator to increase a power level of the pump optical beam to a power level sufficient to amplify the signal optical beam via stimulated Raman scattering (SRS) within the ring resonator. A free carrier concentration in the optical waveguide and the ring resonator is reduced to reduce attenuation of the pump optical beam and the signal beam.
