    摘要: Provided is an apparatus and method for use thereof. The apparatus, in one embodiment, includes first and second 1×N couplers integrated on a substrate and configured to receive an optical symbol having an intended time slot, N being at least three. The apparatus, in this embodiment, further includes N waveguide arms integrated on the substrate, having modulators and coupled between the first and second 1×N couplers. The apparatus, in this embodiment, additionally, includes a modulator controller configured to drive the modulators such that, following transmission over a distance, components of the optical symbol outside of the intended time slot are attenuated relative to components within the intended time slot.

    摘要: Various embodiments of the present invention are directed to color-center-based quantum computer architectures that are both scalable and defect tolerant and to methods for fabricating color-center-based quantum computer architectures. In one embodiment of the present invention, a node of a quantum computer architecture comprises a first photonic device configured to transmit electromagnetic waves, a color center embedded in diamond and coupled to the first photonic device, and a switch located between the first photonic device and a bus waveguide. The switch can be configured to selectively control transmission of electromagnetic waves between the bus waveguide and the color center.

    摘要: An apparatus having a topology that allows building complicated optical programmable arrays useful for manipulating the phase and/or amplitude of an optical signal. Sophisticated filtering and other optical signal processing functionality can be programmed into the array after a chip containing the array has been fabricated. This programming capability is analogous to that of electronic field programmable gate arrays (FPGA's). Apparatus described herein will provide a powerful tool for processing optical signals or very broadband electrical signals.

    摘要: A strip loaded waveguide comprises a slab and a strip, wherein the strip is separated from the slab. Nevertheless, a guiding region is provided for propagating an optical mode and this guiding region extends both within the strip and the slab. A layer of material having an index of refraction lower than that of the strip and the slab may be disposed between and separate the strip and the slab. In one embodiment, the slab comprises a crystalline silicon, the strip comprises polysilicon or crystalline silicon, and the layer of material therebetween comprises silicon dioxide. Such waveguides may be formed on the same substrate with transistors. These waveguides may also be electrically biased to alter the index of refraction and/or absorption of the waveguide.
