Abstract
We study the optical properties of Bi2Te3 and Bi2Se3 topological insulators (TI) nanostructures of various morphologies and geometries, by examining both Far-field and Near-field responses. We find that both the bulk and surface states contribute to the extremely large optical constants of this family. We demonstrate deep subwavelength resonant structures for Bi2Se3 nanobeams and Bi2Te3 metasurfaces..
