▎ 摘　　要

NOVELTY - Depositing graphene on optical fiber end face by light involves preparing graphene solution, immersing to-be-deposited optical fiber end in the graphene solution, making output light of light source enter the optical fiber from the other end in a coupling manner, and controlling deposition shape and thickness of graphene on the optical fiber end face by controlling output power of the light source and action time. USE - Inducing graphene to deposit on optical fiber end face by light (claimed). ADVANTAGE - The process is simple, time consumption is short, small graphene amount is used and is low cost. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of the process of inducing graphene to deposit on optical fiber end face by light.
