▎ 摘  要

Despite the Goos-Hanchen (GH) shifts have recently been discussed in metallic multilayer or dielectric grating structure with monolayer graphene, its investigation on their combined structure is quite limited. In this work, we theoretically propose a new hybrid structure consisting of single layer graphene (SLG), a dielectric grating, a metal film, and one-dimensional photonic crystal (1DPC) and reveal this structure can achieve the GH shift as high as 7430 times of the incident wavelength, which is induced by the surface plasmon resonance (SPR) in the metal layer and the waveguide mode in the 1DPC. Additionally, we find that the positive or negative sign of the GH shift in this structure can be engineering by Fermi energy of SLG, which is unattainable in monolayer graphene based dielectric grating structure. Our results offer the new platform for enhancing and controlling GH shifts.
