    摘要： Structures and methods for cloaking an object to electromagnetic radiation at the microwave and terahertz frequencies include disposing a plurality of graphene sheets about the object. Intermediate layers of a transparent dielectric material can be disposed between graphene sheets to optimize the performance. In other embodiments, the graphene can be formulated into a paint formulation or a fabric and applied to the object. The structures and methods absorb at least a portion of the electromagnetic radiation at the microwave and terabyte frequencies.

    摘要： The present invention is a waveguide photodetector. In one embodiment, the waveguide photodetector includes a waveguide layer where light is guided or is confined and a detection layer formed on the waveguide layer where guided light is detected. Each of the waveguide layer and the detection layer allows for the guiding of no more than a single mode of light for a given polarization. In another embodiment, the waveguide photodetector includes a waveguide layer where light is guided or is confined, a detection layer formed on the waveguide layer where guided light is detected, a first electrical contact coupled to the detection layer, and a second electrical contact coupled to the detection layer. The first electrical contact and the second electrical contact are disposed in a spaced-apart, substantially parallel manner relative to each other.

    摘要： A method of implementing optical deflection switching includes directing a tuning operation at a specific region of coupled optical resonators coupled to an input port, a first output port and a second output port, the coupled optical resonator including a plurality of cascaded unit cells; wherein the tuning operation interrupts a resonant coupling between one or more of the unit cells of the coupled resonators so as to cause an input optical signal from the input port to be directed from the first output port to the second output port.
