NOVELTY - The utility model claims a graphene optical modulator based on bias full medium nano-wire. relating to the field of optical modulation, comprising two full dielectric bias nanowire, waveguide cladding covering the full dielectric bias nanowire, double-layer graphene, capacitor filler between two metal electrodes and double-layer graphene layer. the two full dielectric bias nanowires can realize electromagnetic wave sub-wavelength constraint and improve the interaction of the electromagnetic field and graphene; the double-layer graphene respectively metal electrode contact the 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.
