Abstract

Nanostructures and nanomaterials provide promising building blocks for plasmonic manipulation and applications. To significantly combine the nanostructures with nanomaterials, we have investigated the mid-infrared (MIR) plasmonic response mimicking electromagnetically induced transparency (EIT) in a graphene nanowaveguide system, consisting of the graphene sheets coupling with double graphene ribbons parallel to each other. The results demonstrate that the EIT-like spectral profile and position are strongly dependent on the graphene ribbon width. The resonant spectral width can be effectively controlled by adjusting the coupling strength (gap distance) between the graphene ribbons. Especially, the active tunability of spectral profile can be realized by altering the chemical potential ( or Fermi level) of graphene ribbon. The finite element method (FEM) numerical simulations agree well with the results theoretically calculated by the coupled mode theory (CMT). Our results will offer a new pathway toward the realization of graphene-based active plasmonic controlling and devices.
