Patent ID: 8808972

Claim:
A method of manufacturing a polarizer for a selected wavelength of light, comprising: providing a surface of a layer of a first material of an article, said surface comprising a series of trenches having widths of about 100 nm or less, and depths of at least 50 nm, and filling the trenches to at least 10% of their volumes by sequentially forming a plurality of monolayers of a second material different from the first material within the trenches, and conformally coating the surfaces of the trenches by providing at least one monolayer disposed in the trenches by atomic layer deposition (ALD), and wherein the first and second materials and the trench widths and depths are selected such that the layer transmits about 50% or more of light of the selected wavelength having a first polarization state incident on the layer along a path, and blocks about 80% or more of light of the selected wavelength having a second polarization state incident on the layer along the path, where the first and second polarization states are orthogonal; and the selected wavelength is in the ultraviolet range.
