Electromagnetic Field Coupling Characteristics in Graphene Plasmonic Oligomers: from Isolated to Collective modes

Abstract

In this paper, we propose the plasmonic tetramer composed of the coupled graphene nanodisks. The transformation from the isolated to the collective modes of the proposed structure is investigated by analysing the whispering-gallery modes and extinction spectra with various inter-nanodisk gap distances. In addition, the effect of a central nanodisk into the tetramer on extinction spectra is explored, which leads to the Fano resonance. Furthermore, the refractive index sensing properties of the proposed graphene plasmonic oligomer have been demonstrated. The proposed nanostructures might pave the road toward the applications of graphene plasmonic oligomers such as nanophtotonics, chemical or biochemical sensing.
