▎ 摘  要

NOVELTY - The utility model claims a new mixed plasma optical modulator based on graphene. relating to the field of optical modulation, comprising two dielectric nanowires, a metal nanowire, a waveguide cladding covering the nanowire, a double-layer graphene, a capacitor filler between two metal electrodes and a double-layer graphene layer. nano-wire by dielectric and metal two materials, capable of realizing electromagnetic wave sub-wavelength constraint and improving the interaction of the electromagnetic field and graphene, double-layer graphene respectively metal electrode contact double-layer graphene under the metal electrode electric signal excitation to realize the opening and closing of the light modulator. The utility model can realize high modulation depth, low transmission loss, light modulation of large modulation bandwidth, wide application prospect in the integrated high speed all-optical network.
