| Abstract(in English) | We investigated the dopant concentration and fictive temperature dependencies of Rayleigh scattering in silica-based optical fibers and their glass preforms. The lowest Rayleigh scattering coefficient, which was obtained for a P_2O_5-doped silica perform, was about 80% of the pure silica value. In contrast, the Rayleigh scattering coefficients of F-doped and GeO_2-doped and pure silica glass preforms increased by 5-10% when they were heated to 1800℃ because the density fluctuation is proportional to their fictive temperature. We also obtained very low Rayleigh scattering coefficients in fabricated fibers by controlling the composition of preforms or the fiber drawing conditions. We used these results to reevaluate the intrinsic losses of P_2O_5-doped, pure, and GeO_2-doped silica core fibers by using the Rayleigh scattering coefficients of performs, and found them to be 0.095-0.130dB/km at 1.55μm. |
