摘要： A fully integrated waveguide-based, efficient surface plasmon coupler composed of a realistic non-tapered dielectric waveguide with graphene patches and sheet is designed and optimized for the infrared. The coupling efficiency can reach nearly 80\% for a coupler as short as 700 nm for an operating wavelength of 12 $\mu$m. This \gui{work} is carried out \gui{using rigorous numerical models} based on the finite element method \gui{taking into account 2D-materials as surface conductivities}. \gui{The} key numerical results are \gui{supported by} phdisplaycopyrightysical arguments based on modal approach or resonance condition.
