▎ 摘　　要

NOVELTY - The Octonacci photonic crystal and graphene composite structure has a single-layer graphene which is embedded on an interface of two adjacent dielectric thin film in an Octonacci photonic crystal to form a composite structure of the Octonamic crystal and the graphene. A TM light is incident into the composite structure from a left side. An incident angle is represented by a symbol. A symbol is represented as incident light. An optical fractal resonance state is supported by the graphene and an optical sub-form. USE - Octonacci photonic crystal and graphene composite structure for a GH displacement application wavelength sensor of an all-optical communication system. ADVANTAGE - The graphene enhances the reflectivity of the optical sub-form. The high sensitivity wavelength sensor near a set of central wavelengths can be obtained by using the quasi-photonic crystal in graphene composite, using optical fractal effect and reflection coefficient phase violent change, realizing large space Goos-Hansen displacement. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of an octonacci photonic crystal and graphene composite structure.
