NOVELTY - This utility new type patent claims a coupling waveguide hybrid plasmonic waveguide polarization beam splitter based on graphene, comprising: SiO2 substrate and two parallel placed on the substrate of Graphene-SiO2-Si hybrid plasmonic waveguide, wherein the left side of the input waveguide is single-side convex hybrid plasmonic waveguide, is located at the right side of the strip-shaped waveguide from the exciting element is common mixing. polarizing beam splitter uses the single-side convex hybrid plasmonic waveguide plasmon waveguides are combined with common type mixing method, so that in the long wavelength of working condition, mixing of input waveguide capable of supporting TE and TM mode plasmon waveguide mode excitation and transmission, so it has high integrated degree, strong limiting ability and so on.
