▎ 摘　　要

NOVELTY - The fiber has an optical fiber body provided with an inner fiber along axial direction. Two ends of the optical fiber body are provided with a single or multiple air hole. Each air hole is covered with a graphene film. The graphene film is electrically connected with an optical surface. Two ends of the optical fiber body are covered on a surface of the graphene film. The two ends of the optical fiber are provided with the each air hole. The optical fiber body is selected from one of an internal reflection photonic crystal fiber, a photonic band gap photon crystal fiber and a hollow fiber. USE - Graphene porous fiber. ADVANTAGE - The fiber is convenient to use, and has wide working frequency band and high modulation efficiency, and reduces energy consumption rate. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a graphene fiber electro-optic modulator modulating method. DESCRIPTION OF DRAWING(S) - The drawing shows a side perspective view of a graphene porous fiber. '(Drawing includes non-English language text)'
