▎ 摘　　要

NOVELTY - The hybrid waveguide structure has an upper half waveguide structure and a lower half waveguide structure. The lower half waveguide structure comprises a lower layer of low refractive index dielectric (110) and the lower layer of low refractive index dielectric of graphene (120). The upper half waveguide structure has a low refractive index dielectric located on the graphene and a high refractive index dielectric (130) located on the low refractive index dielectric. The low refractive index dielectric is high density polyethylene (HDPE). The high refractive index material is gallium arsenide (GaAs). USE - Hybrid waveguide structure for graphene. ADVANTAGE - The graphene-based hybrid waveguide structure has high refractive index. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the hybrid waveguide structure. Low refractive index dielectric (110) Low refractive index dielectric of graphene (120) High refractive index dielectric (130)
