Abstract
An optical waveguide comprising a first polymeric layer and a second polymeric layer adjacent to the first polymeric layer and a method for making the optical waveguide are disclosed. The first polymeric layer has a refractive index of n1 and solubility S1 in a first solvent. The second polymeric layer has a refractive index of n2 and solubility S2 in the first solvent. In the optical waveguide, n1 ≠n2 and S1/S2 is at least 5.
