Method for producing optical waveguide containing image fiber.

摘要

A method for producing an optical waveguide comprising a core made of a transparent polymer and a cladding made of a polymer having a lower refractive index than that of the core and containing an image fiber therein, which comprises polymerizing a monomer for the transparent polymer in an atmosphere not containing oxygen and co-extruding the transparent polymer melt around the image fiber and the cladding material around the transparent polymer, by which an optical waveguide having good light transmission characteristics is produced.
