▎ 摘　　要

We study a hybrid graphene plasmonic device that consists of a gold nanostripe array combined with graphene. We have measured significant changes in the optical properties of the nanostripe array after the transfer of monolayer or bilayer graphene on the top of it. We suggest that this modification is partly due to the resistive coupling of localized plasmon resonances through the highly mobile electrons of the graphene layer. Our results open up new possibilities for designing active optical elements to exploit the high sensitivity of graphene carrier-density to bias voltage for ultra-fast light modulation. This is especially interesting as the plasmonic resonances of metal nanostructures can lie in the visible, NIR and UV; important areas for many applications.
