NOVELTY - The utility model claims a composite structure of picture-Eritrea sequence multi-layer dielectric and graphene, belonging to the technical field of all-optical communication system. comprising two symmetrically distributed composite component, the composite component comprises a graphene layer, several first dielectric layer and several second dielectric layer, the graphene layer in the composite component, the arrangement rule of the first dielectric layer and the second dielectric layer is as follows: from outside to inside in turn is a first dielectric layer, a second dielectric layer, a graphene layer, a second dielectric layer, a first dielectric layer, a second dielectric layer, a first dielectric layer, a first dielectric layer and a second dielectric layer. The utility model can realize optical tri-stable state and multi-stable state.
