Abstract
Methods for improving the manufacturing of optical gratings and surface relief grating structures are described. An optical grating may be formed by spin coating a liquid monomer solution that includes a solvent, a liquid monomer, and a nanoparticle filler with a higher refractive index than the liquid monomer on a substrate. The optical grating may be formed by pressing a mold that includes nanostructures on its surface into the liquid monomer to form gratings and then hardening the liquid monomer while the mold is held within the liquid monomer. After the mold has been pressed into the liquid monomer, two regions within the liquid monomer may be formed: a first region that includes the gratings and that does not include nanoparticles (or that includes less than a threshold number of nanoparticles) and a second region arranged below the gratings that includes nanoparticles.
