Tunable plasmonically induced transparency with unsymmetrical graphene-ring resonators

Abstract

Articles you may be interested in Low-power, ultrafast, and dynamic all-optical tunable plasmonic analog to electromagnetically induced transparency in two resonators side-coupled with a waveguide system Plasmon-induced transparency in metamaterials: Active near field coupling between bright superconducting and dark metallic mode resonatorsThe multi-wavelength tunable plasmonically induced transparency (PIT) phenomena in two-ring and three-ring systems at infrared range were theoretically and numerically investigated. In the two-ring system, changing the bias voltage of graphene ring or the separation between graphene rings would induce an off-to-on PIT optical response. An asymmetry factor has been introduced to explain the corresponding transmission spectra. In the three-ring system, by bringing in a new asymmetry factor, multiple new PIT windows would arise at the left or right side of the original PIT windows. Numerical simulation by finite element method was conducted to verify our designs. Those proposed structures hence have potential in ultra-compact graphene optoelectronic devices at the infrared range. V C 2015 AIP Publishing LLC. [http://dx.

Dynamically Tunable Plasmon-Induced Transparency in On-chip Graphene-Based Asymmetrical Nanocavity-Coupled Waveguide System

“…Specifically, the chemical potential of graphene can be tuned via chemical doping or electrical gating [25, 26]. Mikhailov et al have experimentally shown that the carrier density in a graphene sheet as high as 10 14  cm −2 had been achieved, which led to a chemical potential of 1–2 eV at a temperature below 250 K [40].…”

“…These remarkable and outstanding properties in turn enable a utility optical material in optoelectronic applications. In recent years, great attention has been focused on graphenebased plasmonic waveguides [23][24][25][26][27]. de Abajo et al have researched the propagation properties of graphene plasmonic waveguide constituted by individual and paired nanoribbons [28].…”
