Tuneable paired nanoribbons with graphene for single and multiple transparency windows

Abstract The existence of multiple electromagnetically induced transparencies (EIT)-like spectral responses is proved in graphene in this paper. Transmission spectra of a series of graphene nanoribbon layers with different widths are studied. It is found that placement, number and size of transparency peaks can be influenced by the graphene ribbons width. Additionally, multiple EIT-like spectral responses can be obtained by adding more unit cells of graphene ribbons in the plasmonic structure. Our results suggest that the demonstrated EIT-like based on graphene plasmonic may offer possibilities for optical switching.
