Organic polymer optical waveguide absorption type light modulator based on buried graphene electrode

The invention provides an organic polymer optical waveguide absorption type light modulator based on a buried graphene electrode, which belongs to the technical field of planar light waveguide absorption type light modulators based on graphene. The light modulator is composed of a substrate layer, an organic polymer waveguide lower cladding layer, a first organic polymer waveguide core layer, a first graphene layer, a dielectric insulating layer, a second graphene layer, a second organic polymer waveguide core layer, an organic polymer waveguide upper cladding layer, a left electrode and a right electrode. According to the invention, an organic polymer material is used to design a waveguide structure; the graphene layers are transferred to the middle of the waveguide core layer, so that the interaction of graphene with light is enhanced to achieve faster carrier migration rate; the working rate of the light modulator is improved; when the organic polymer material without electro-opticeffect is used, a graphen
