Plasmonic enhancement of material properties

摘要

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).

主权项

1. A plasmonic structure comprising:
a substrate; an electrically conductive film disposed on the substrate, the film defining an outer face, the film also defining at least one nanoslit extending through at least a portion of the thickness of the film, the nanoslit defining opposing sidewalls; and an effective amount of an electrochromic material disposed on the sidewalls of the nanoslit.
