Abstract
Official abstract text for this publication.
A broadband optical beam splitter can comprise a non-metallic high contrast grating including a substrate and an array of posts attached to a surface of the substrate. The grating can have a subwavelength period with respect to a preselected optical energy wavelength, the preselected optical energy wavelength within the range of 400 nm to 1.6 μm. Additionally, the broadband optical beam splitter can have a bandwidth of 80 nm to 120 nm and can have an optical energy loss of less than 5%.
First claim
Opening claim text (preview).
What is claimed is: 1. A broadband optical beam splitter, comprising a non-metallic high contrast grating including a substrate and an array of posts attached to a surface of the substrate, wherein the grating has a subwavelength period with respect to an optical beam having a preselected optical energy wavelength range within the range of 400 nm to 1.6 μm, and wherein the broadband optical beam splitter has a bandwidth of 80 nm to 120 nm and exhibits an optical energy loss of less…
