Abstract
Abstract An apparatus and method are provided for converting light into a surface plasmon polariton on a plasmon supporting nanostructure and then controlling the emission of the re-emitting light. A circuit component is also described that is constructed of a nanostructure, which is comprised of at least one plasmon supporting metal. The metal can propagate the light, as a surface plasmon polariton, through the one-dimensional nanostructure and re-emit the light. The metal is a plasmon supporting metal, for example but not limited to, gold, silver, copper, and aluminum.
