Abstract
In certain aspects, the disclosure relates to articles that include a plurality of walls configured to form a grating. Each of the plurality of walls can include a layer of a first material and a layer of a second material different from the first material. The articles can retard incident radiation at wavelengths λ1 and λ2 by amounts Γ1 and Γ2, respectively, where |λ1−λ2| is about 15 nm or more and Γ1 is substantially equal to Γ2.
