A Detailed Study of a Dielectric Waveguide Structure for an Enhanced Evanescent Wave Atom Mirror
Abstract
We are interested in a coherent atom mirror (specular atomic reflections in vacuum). A resonant dielectric waveguide structure is placed upon the prism so that a large energy is confined into the waveguide which is placed between two mediums of low index medium. The incident laser beam is resonantly coupled to a waveguide mode, through the gap, by frustrated total internal reflection. We obtain a large amplitude evanescent wave in the vacuum above the waveguide. We study the influence of the thickness of the gap and the losses inside the waveguide.
