Fluoropolymers consisting of alternating perfluorocyclobutane and aryl ether linkages possess suitable properties for optical waveguides and other devices using refractive properties of the polymers. Perfluorocyclobutane (PFCB) polymers having aryl groups alternating on an ether chain have shown use

Fluoropolymers consisting of alternating perfluorocyclobutane and aryl ether linkages possess suitable properties for optical waveguides and other devices using refractive properties of the polymers. Perfluorocyclobutane (PFCB) polymers having aryl groups alternating on an ether chain have shown useful physical properties for optical waveguide applications. Processes for micromolding such polymeric films by replicating a pattern or image directly from a silicon master, rather than from a polydimethyl siloxane (PDMS) mold, are disclosed.
