Refraction of amorphous copolymers of perfluoro-2,2-dimethyl-1,3-dioxole and perfluoropropylvinyl ether within a telecommunication wavelength ranges near 1300 and 1550 nm

Amorphous copolymers of perfluoro-2,2-dimethyl-1,3-dioxole and perfluoropropyl vinyl ether were synthesized by ultrahigh pressure method without using of initiators. By applying spectroscopic refractometry method, authors measured the refraction (refractive index n(l) and material dispersion dn(l)/dl, where l is a wavelength of optical copolymers radiation) within a telecommunication wavelength ranges near l = 1300 and 1550 nm. It is shown that it have low values of n(l) and small material dispersion dn(l)/dl. Synthesized copolymers can be used as a cladding of silica fibers for high-speed optical information transmission systems, as well as a cladding of waveguides made of fluorine-containing electro-optical polymers for high-speed light modulators.
