Abstract
An optical waveguide and method of fabricating waveguide structures is disclosed. More specifically, a method of producing an organic waveguide which comprises treating a transparent plastic substrate with a solution in a inert solvent of an organic dopant which is absorbed into the surface of the substrate, under conditions such that a surface layer is formed having a refractive index which is greater than that of the substrate. Said dopant has a higher affinity for the plastic's substrate than for the solvent.
