Abstract:
A method of forming a polymeric optical coating upon a substrate comprising the steps of:a) providing a substrate, a deposition chamber and a gaseous hydrocarbon; b) placing said substrate within said chamber and introducing said gaseous hydrocarbon into said chamber; c) reducing the pressure within said chamber; d) applying an electric current to said chamber ranging from approximately 1.0 to 1.8 watts/cm2 of said substrate such that said gaseous hydrocarbon is caused to disassociate into bi-products; e) forming a layer upon said substrate from the bi-products produced in step (d); and f) doping said layer formed in step (e) with a polar material selected from the group consisting of germanium and silicon for forming the optical coating.
