Abstract
Official abstract text for this publication.
A system includes a non-uniform grating having a first region with a first refractive index and second regions with a second refractive index. A pattern of the second regions varies with an angular coordinate such that phase shifts of an incident beam created by the grating cause destructive interference that creates an intensity minimum within an output beam from the grating.
First claim
Opening claim text (preview).
What is claimed is: 1. A system comprising a non-uniform grating having: a first region that has a first refractive index; and second regions that have a second refractive index, wherein in a polar coordinate system that is parallel to a beam-incident-face of the grating, a center-to-center spacing in a radial direction between the second regions varies according to an angular coordinate such that phase shifts created by the grating in an incident beam on the grating cause destr…
