Abstract (en)

[origin: WO9811287A1] The present invention is an improved method involving microwaves for making polymer optical fiber cable and graded index optical fibers. The polymer can be any shape including, but not limited to, sheets, films or cable. The present invention also includes improved polymer optical fibers that incorporate quinine and quinone based compositions that shift the wavelength of radiation from ultraviolet radiation to visible radiation.
