Redox-Tunable Conducting Polymer Plasmonics and Metasurfaces

We recently introduced conducting polymers as a new type of redox-tunable plasmonic materials,¹ opening for chemically and electrically controlled nanooptics and metasurfaces.^2-3 I will present the background to this emerging area of nanooptics and discuss recent results. As example of unique opportunitues enabled by conducting polymers, I will show how aligning the polymer chains by straining can induce redox-tunable in-plane hyperbolic permittivity and broadband chirooptics.^{4, 5} I will also discuss requirements, possibilities and limitations in extending this research area to materials beyond PEDOT-based systems.⁶
