The polymeric nanoantennas provide complete and reversible on/off switching as well as possibility for gradual tuning. <LINK> We utilized the possibility to tune the charge carrier density of conducting polymers by orders of magnitude via their redox state, and could thereby switch the material of the nanoantennas between metallic/plasmonic and dielectric. The system provides convenient electrical control of the nanoantennas, building on our previous demonstration of chemical switching of conducting polymer nanoantennas. #PEDOT #Plasmonics #Metasurfaces <LINK>",https://arxiv.org/abs/2108.04045,"Nanostructures of conventional metals offer manipulation of light at the nanoscale but are limited to static behavior due to their fixed material properties. To develop the next frontier of dynamic nanooptics and metasurfaces, we utilize the redox-tunable optical properties of conducting polymers, which were recently shown to be capable of sustaining plasmons in their most conducting oxidized state. Using nanodisks of poly(3,4-ethylenedioxythiophene:sulfate) (PEDOT:Sulf) as a model system, we present the first electrically tunable conducting polymer nanooptical antennas. In addition to repeated on/off switching of the polymeric nanoantennas, we demonstrate the possibility for gradual electrical tuning of their nanooptical response, which was found to be related to the modulation of both density and mobility of the mobile polaronic charge carriers in the polymer. The presented concept takes important steps towards electrically tunable metasurfaces with truly dynamic optical nanoantenna pixels, with not only varying farfield but also tunable nearfield. The work paves the way for applications ranging from tunable flat metaoptics to adaptable smart windows.
