A low-loss GI plastic optical fiber in which the attenuation of transmission was about 130 dB/km at 650 nm wavelength was successfully obtained by a new interfacial-gel copolymerization technique. Novel optical functional polymer glasses, such as birefringence-free copolymers for any degree of orientation and optically active amorphous polymers which act as polarization modulators, were synthesized and characterized.
