description The invention discloses a graphene metasurface photonic crystal surface wave optical device for realizing wavelength regulation and control. The cross section of the graphene metasurface photonic crystal surface wave optical device comprises a coating layer, a graphene metasurface and a multilayer film structure element. By adjusting the refractive index or the thickness of the coating layer or a certain layer structure, light is input at a specific angle to be incident to the surface of the optical device, a remarkably enhanced light field is limited on the graphene metasurface, the interaction between graphene and light is enhanced, transmission and spatial distribution of the photonic crystal surface wave light field are controlled by using the metasurface micro-nano structure, and the photonic crystal surface wave light field transmission efficiency is improved. Amplitude, phase and frequency response are modulated, and frequency selection and wavelength regulation and control effects are realized, so tha
