NOVELTY - This utility model claims a graphene optical detector, referring to the optical detector. The invention claims a graphene light detector based on super material structure of realizing function of super bandwidth absorbing. it is an overlapped structure, from up to down in turn is metal layer-dielectric layer-graphene layer-medium layer-graphene layer-medium layer-graphene layer-medium layer-graphene layer-medium layer-graphene layer-medium layer-graphene layer-medium layer-graphene layer-medium layer-graphene layer-medium layer-graphene layer-medium layer-graphene layer-medium layer-graphene layer-medium layer-graphene layer structure in the vertical direction, in the horizontal direction, the graphene layer and the medium layer are made of block, arranged in the block period on each graphene layer added bias voltage for changing the refractive index of graphene, thereby dynamically adjusting space reflectivity of each graphene layer, so as to adjust space rate of the whole structure.
