High-bandwidth graded-index polymer optical fibre☆

Abstract A low-loss and high-bandwidth graded-index (GI) polymer optical fibre in which the attenuation of transmission was less than 150 dB km−1 at 650 nm wavelength and the bandwidth was several hundred megahertz kilometres has been successfully obtained by a copolymerization process utilizing the difference of the monomer reactivities. The control of the refractive-index profile and the light scattering of such GI materials are theoretically and experimentally investigated.
