▎ 摘　　要

NOVELTY - The waveguide has a silicon waveguide core placed in the center of the plasmon waveguide, a silicon dioxide waveguide sandwich layer wrapped around the silicon waveguide core, and a graphene waveguide cladding layer wrapped around the outer layer of the silicon dioxide waveguide sandwich layer. USE - Cylindrical hybrid plasmon photonic waveguide with adjustable polarization state based on graphene. ADVANTAGE - The waveguide realizes limiting transmission of radial polarized light and the rotating polarized light of the column vector light. DESCRIPTION OF DRAWING(S) - The drawing shows a cross-sectional schematic diagram of the cylindrical hybrid plasmon waveguide with adjustable polarization state based on graphene.
