Abstract

Various plasmonic structures in the form of electrochromic optical switches are described which exhibit relatively high optical switching contrast. The switches generally include a collection of nanoslits formed in a thin electrically conductive film. An electrochromic material is disposed on the conductive film and along the sidewalls of the nanoslit(s).
