Method of making graded refractive index polymeric optical fibers and optical fibers made by the method
 A continuous manufacturing method is provided by extruding a composite optical fiber from two polymeric solutions containing two different monomers having different refractive indices, and then allowing the monomers to diffuse in a diffusion region such that the two monomers are diffused into each other before the optical fiber is hardened.
