▎ 摘　　要

NOVELTY - The modulator has a D-type optical fiber whose optical fiber cladding is stripped with a certain thickness on one side so that the optical fiber cladding thickness of the fiber core at the stripping position is 0.8-1.2 microns. The optical fiber cladding outside the self-stripping fiber core is orderly provided with the following laminated structure along the radial direction. The optical fiber cladding outside the self-peeling off is orderly a first layer graphene layer (1) along the radial direction, a dielectric layer (3), a second layer graphene layer (9). USE - Used enhanced graphene electro-absorption modulator based on D-type fiber. ADVANTAGE - The modulator: has strong interaction strength; has low production cost; and retains the excellent characteristics of optical fiber interconnection. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of the enhanced graphene electro-absorption modulator based on D-type fiber. First layer graphene layer (1) Dielectric layer (3) Second layer graphene layer (9)
