Manipulation of infrared light in graphene nanostructures

Abstract

We have investigated the mid-infrared plasmonic propagation characteristics in several graphene nanostructures. It is found that the Fano resonance and nanofocusing effects can be realized by tailoring the dielectric substrate and graphene. Moreover, these optical performances are dependent on the relevant physical parameters. The optical behaviors of graphene could pave a new pathway towards the manipulation of mid-infrared light at nanoscale.
