Abstract
Official abstract text for this publication.
A leaky-mode resonant retarder is described. The retarder may include a substrate and a spatially modulated periodic layer coupled to the substrate, where the spatially modulated periodic layer is configured to shift a phase between two perpendicular electric-field components of incident light. The retarder may operate as a half-wave plate or a quarter-wave plate.
First claim
Opening claim text (preview).
What is claimed is: 1. A leaky-mode resonant retarder, comprising: a substrate; and a spatially modulated periodic layer coupled to the substrate, where the spatially modulated periodic layer is spatially modulated in a direction perpendicular to a normal of the substrate and creates a leaky-mode waveguide, and where the spatially modulated periodic layer is configured to shift a phase between two perpendicular electric-field components of incident light by a prespecified amo…
