Abstract

Easily tunable photonic and especially plasmonic devices have been an elusive and highly anticipated goal for the scientific community. Graphene is a promising candidate for covering this gap in the field of plasmonics and offering new exciting physics as well as commercial devices. The band structure of Graphene allows for dynamical and efficient conductivity tuning providing easy control of electrical and optical characteristics of the material [1]–[3]. Plasmon excitations are directly depended on the conductivity of the material and thus dynamic electrostatic tuning of the properties of Graphene can provide efficient control over both the frequency of plasmon oscillations and the level of absorption from plasmon excitations [4].
