▎ 摘　　要

NOVELTY - The tuner has a graphene thin film (1) and a grate area arranged with an optical fiber and an optical grating mode leakage site (2), respectively. The graphene thin film is arranged with the leakage mode site area of the fiber optical grating device and the optical grating mode leakage site through a wet transfer coating grade. USE - Graphene assistant full-driving fiber optical grating tuner for use in an optical communication field, an optical filter, a sensor detection field and a laser technique field. ADVANTAGE - The tuner is simple to manufacture, compact in structure and inexpensive, and has high tuning efficiency, high responding speed and strong stability. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for the following: (1) a graphene assistant full-driving fiber optical grating tuner reflection spectrum demarcating method (2) a light path system implementation method. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a graphene assistant full-driving fiber optical grating tuner. Graphene thin film (1) Optical grating mode leakage site (2)
