NOVELTY - The utility model claims a graphene-nano fibre of high speed travelling wave electro-optic modulator, comprising micro-nano optical fibre top layer graphene, right side electrode, a substrate, a left side electrode, a medium layer, a graphene layer, the left side electrode and a right side electrode is coplanar with structure of travelling-wave electrode, on the substrate layer, said micro-nano optical fibre arranged between the top layer graphene and graphene layer, and located coplanar with the electrode, the dielectric layer isolating the top layer graphene and bottom layer graphene. The utility model has stable operation, easy integration, low power consumption and so on. and existing lumped graphene-nano fibre, the traveling wave electrode in this utility model obviously improves the modulation bandwidth. simple preparation, and capable of efficiently connecting a standard single mode optical fiber communication network, method by interferometer, or a directional coupler and so on, it can be widely applied to optical intensity modulation in the optical communication field has large effect.
