Optical nanoantennas, the building blocks of metasurfaces, can manipulate light at the nanoscale. While metallic or high-index dielectric materials have been widely exploited for nanoantenna research, organic materials have been marginalized due to their negligible interaction with light as well as problematic nanofabrication methods. However, recent studies based on newly emerging materials and methodologies have shown a potential use of organic materials in the field of nanooptics. In this presentation, nanoantennas based on both metallic and semiconducting organic materials will be presented. The unique functionalities provided by these new types of optical nanoantennas may open up a route for applications such as large-area, flexible, fully-organic metasurfaces for tunable meta-optical components, bio-sensors, smart windows, etc.
