▎ 摘　　要

NOVELTY - The absorber has a substrate (1) whose upper surface is fixed with a containing groove (10) that extends to two ends of the substrate along X-direction. A silica optical waveguide (4) is located in the containing groove. The silicon dioxide optical waveguide is fixed by a cantilever (5) that is fixed at a side wall of the containing groove. Two ends of the silicon dioxide optical waveguide are connected with a light input device (2) and a light output device (3). A graphene film (6) is covered on the silicon dioxide optical waveguide. Two sides of the graphene film are coated on a surface of the substrate along Y-direction. USE - On-chip Silicon dioxide optical waveguide integrated Graphene saturable absorber. ADVANTAGE - The absorber enhances interaction force between the graphene film and an optical waveguide transmission mode, and improves saturation absorption extinction ratio. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for an On-chip Silicon dioxide optical waveguide integrated Graphene saturable absorber manufacturing method. DESCRIPTION OF DRAWING(S) - The drawing shows a side sectional view of an on-chip silicon dioxide optical waveguide integrated graphene saturable absorber.
