Claim 0:
1. An optical element comprising:
a substrate having a first refractive index; and
a pattern of periodically repeating structures formed on the substrate and configured to diffract light, the structures having a second refractive index greater than the first refractive index, the structures comprising a polymer-based material that includes a polymer and inorganic material comprising one or more of a metal oxide, a metal nitride, and a metal oxynitride, wherein the inorganic material is incorporated within the polymer, wherein adjacent structures of the pattern of periodically repeating structures are separated by respective spaces such that the polymer-based material extends discontinuously over the substrate and a surface of the substrate is exposed in the spaces.
