ABSTRACT:
A method of forming optical waveguides is described in which a film of a novolac resin is deposited on a transparent substrate and a dopant material is incorporated into the film during or after the coating step. Additional quantities of the same or different dopant may be incoporated into the dried film by solvent assisted indiffusion.
