▎ 摘　　要

NOVELTY - The modulator has an optical modulator body formed on a substrate (10) and provided with a dual-layer graphene lithium niobate light waveguide (202), where the optical modulator body is equipped with a first electrode (301), a second electrode (302), a light input terminal and a light output terminal. An end surface of a first graphene layer (201) is extended to an edge surface of the substrate and embedded with the first electrode. An end surface of a second graphene layer (203) is extended to another edge surface of the substrate and embedded with the second electrode. USE - Graphene-lithium niobate multi-layer structured hybrid integrated optical modulator. ADVANTAGE - The modulator is small in size, and reduces insertion loss, and has high optical modulating efficiency, high response rate and high working bandwidth rate. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a graphene-lithium niobate multi-layer structured hybrid integrated optical modulator manufacturing method. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a graphene-lithium niobate multi-layer structured hybrid integrated optical modulator.
