Theory of evanescent plasmon-mode optical lattices with metallic layer

Abstract

How a surface <span style="mso-bidi-font-weight:bold">plasmon optical lattice can be produced when an ordinary Hermite-Gaussian light is totally reflected internally at the planar surface of a dielectric on which the finite thickness of metallic layer has been deposited, has been studied in the present paper. <span style="mso-bidi-font-weight:bold">The characteristic property of such a light is the exponential decay with distance in a vacuum which can basically provide<span style="mso-bidi-font-weight:bold"> a two-dimensional optical lattice with attractive enhancements<span style="mso-bidi-font-weight:bold"> with the strongly trapped intensity distribution decays with distance vertical to the metallic surface. The detailed characteristics of this lattice structure depend on the input light parameters and the dielectric mismatch of the media. As well as this, they can be controlled by varying the incident angle and the order of the Hermite-Gaussian light.
