Abstract

We investigate a coupled graphene resonator system which exhibits multiple mode-splitting effects and electromagnetically-induced-absorption-like transmission. The finite element method has been employed to study the transmission and electromagnetic responses of our designs at mid-infrared frequency. According to simulation results, the mode-splitting effects are mainly dependent on the destructive interference between two graphene resonators. By varying the chemical potential of graphene or the coupling gap, we are accessible to achieve a dynamically controllable mode-splitting system serving as a sensing application.
