Embodiment Construction
[0023] Such as figure 1 , figure 2 As shown, the all-fiber electro-optic modulator based on graphene materials includes single-mode fiber 1, silica grooved substrate 2, Al 2 o 3 A transition thin layer 4, a graphene film 5, a single-mode optical fiber 1 is arranged on a silica grooved substrate 2, and is fixed with an encapsulated epoxy glue, and a groove 3 is arranged on the single-mode optical fiber 1, and the groove 3 With Al 2 o 3 Transition thin layer 4, Al 2 o 3 A graphene film 5 is arranged on the transition thin layer 4 .
[0024] The single-mode optical fiber 1 includes an optical fiber core layer 101 and an optical fiber cladding layer 102 .
[0025] The steps of the manufacturing method of the all-fiber electro-optic modulator based on graphene material comprise as follows:
[0026] 1) First place a single-mode optical fiber 1 with a diameter of about 125um into the groove of a silica grooved substrate 2 that matches the outer diameter of the optical fiber,...
