Abstract
A method for recording a diffractive nanostructure is provided. The method includes: providing a holographic recording mixture including a monomer, an inert material, and a photoinitiator; depositing a layer of the mixture onto a substrate; exposing the mixture to a holographic recording beam to form a nanostructure of polymer regions and inert material regions within the mixture layer; and depositing a surface-conditioning optical layer on top of the nanostructure after curing of the expose mixture.
