Abstract(in English) | The effect of the thermal treatment of silica-based glasses and glass fibers on their Rayleigh scattering is investigated experimentally. The Rayleigh scattering coefficients of bulk glasses are found to be increased 5~10% by heating them to 1800℃ because the density fluctuation is in proportion to their fictive temperature. Based on these results, we propose a method for reducing the Rayleigh scattering losses of silica-based optical fibers by drawing them slowly at low temperatures. We used this method to obtain a GeO_2 doped silica core single-mode fiber with a minimum loss of 0.16dB/km at 1.55μm. As a result, we confirmed that the reduction in the fictive temperature of silica-based glasses and glass fibers has an effect on reducing their Rayleigh scattering. |
