▎ 摘　　要

NOVELTY - The method involves performing graphene oxide film surface moisture evaporation process. A surface of an optical fiber is polished. Optical fiber grating manufacturing process is performed. Laser light is emitted by using a purple light laser. A graphene oxide film is deposited on the optical fiber. Graphene oxide film polishing process is performed to form an amplitude mask. Optical fiber graphene oxide reducing process is performed by using a column lens. The graphene periodic structure layer is formed between a cladding and the optical fiber. USE - Laser-based reduction-oxidation graphene micro-structure cladding filter manufacturing method. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a laser-based reduction-oxidation graphene micro-structure cladding filter.
