▎ 摘　　要

NOVELTY - The polarizer has an optical fiber (1), where surface of a core (2) of the optical fiber is coated with a graphene thin film (3). The graphene thin film is coated with a refractive index matched polymer i.e. polymethylmethacrylate or UV curing resin. The surface of the core of the optical fiber is formed with a Bragg grating structure. Length of the graphene thin film is 10 mm. The graphene thin film is formed in a single layer or multiple layers. USE - Graphene coated optical fiber polarizer. ADVANTAGE - The polarizer lowers the scattering loss and component insertion loss. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a graphene coated optical fiber polarizer.
