Abstract
Official abstract text for this publication.
An inorganic, dielectric grid polarizer device includes a stack of film layers disposed over a substrate. Each film layer is formed of a material that is both inorganic and dielectric. Adjacent film layers each have different refractive indices. At least one of the film layers is discontinuous to form a form-birefringent layer with an array of parallel ribs having a period less than 400 nm. Another layer, different than the form-birefringent layer, is formed of an optically absorptive material for the ultra-violet spectrum.
First claim
Opening claim text (preview).
The invention claimed is: 1. An absorptive, ultra-violet, inorganic, and dielectric grid polarizer device, the device comprising: a) a substrate; b) an absorptive layer disposed over the substrate including an optically absorptive material to an ultra-violet spectrum; c) the absorptive layer being formed of a material that is both inorganic and dielectric; d) the absorptive layer having a different refractive index than a refractive index of the substrate; e) the absorptiv…
