Dynamic Conducting Polymer Optics and Plasmonics

Redox-tunable conducting polymers offer novel ways for dynamic control of light. Not least, the possibility to dynamically switch such materials between optically metallic and dielectric states has enabled dynamically tunable plasmonic nanoantennas and metasurfaces.^1-3 Other areas ranges from reflective color displays^4-5 to dynamic radiative cooling⁶ and adaptive camouflage⁷. This presentation will cover our most recent work on those topics, including extension to n-type polymer plasmonics⁸ and exploration of in-plane hyperbolic conducting polymers for dynamically tunable broadband chiroptics,^9-10
