▎ 摘　　要

NOVELTY - Photonic crystal based on stack of laser-etched graphene films comprises multiple double-layer crystal structures stacked together. The double-layer crystal structure has a glass substrate and a graphene film (2). The glass substrate has a hollow interior and a rectangular outer periphery. The graphene film is adhered and covered on the glass substrate, and width is consistent with the outer width of the glass substrate. The area on the graphene film corresponding to the hollow part of the annular glass substrate is provided with periodic microstructure patterns. The two-layer crystal structure forms a graphene film layer and an air layer. The thickness of the air layer can be adjusted by changing the thickness of the glass substrate. The thickness of the graphene film layer can be adjusted by changing the thickness of the graphene film. The periodic microstructure pattern on the graphene film is made according to the design pattern by laser etching. USE - Used as photonic crystal based on stack of laser-etched graphene films. ADVANTAGE - The method: quickly prepares photonic crystals; is simple and easy to realize; quickly realizes the size of the designed microperiod structure, the etching pattern and other parameters; realizes the control of the propagation of light of different frequencies in the photonic crystal; and has excellent design flexibility and parameter adjustability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for processing method of the photonic crystal based on stack of laser-etched graphene films. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of the photonic crystal based on stack of laser-etched graphene films. Graphene film (2)
