▎ 摘　　要

NOVELTY - The polarizer has an optical fiber provided with an optical fiber core, a graphene thin film layer, package resin i.e. low refractive index UV glue, and a D-type groove that is formed with the graphene thin film layer, where the graphene thin film layer is formed to the optical fiber core and the groove by encapsulation glue. USE - Graphene thin film-D-type optical fiber broadband optical polarizer. ADVANTAGE - The polarizer has small size, simple preparation effect and high extinction ratio. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a graphene thin film-D-type optical fiber broadband optical polarizer.'(Drawing includes non-English language text)'
