Abstract
The present invention is directed to refractive index contrast ('RIC') polymers and methods for producing and using the same. In one particular embodiment, RIC polymers of the invention can be used as waveguides. RIC polymers of the invention are produced from a monomeric mixture comprising a first monomer and a second monomer comprising an acid-labile protecting group, where a first polymer produced from the first monomer has a different refractive index compared to the refractive index of a second polymer produced from the second monomer. The base refractive index of RIC polymers can be tuned by controlling the amount of the first and the second monomers. Furthermore, the refractive index of the waveguide can be modulated by the amount of acid-labile protecting group removal.
