Abstract :
The Rayleigh scattering and infrared absorption losses of P2 O5-F-doped silica glass, which is a candidate material for ultra-low-loss optical fiber, were investigated experimentally. The Rayleigh scattering loss of 8.5 wt.% P2O5 and 0.3 wt.% F-doped SiO2 glass is found to be 0.8 times that of pure silica glass. It is also found that the infrared absorption property of P2O5-F-SiO2 glass is almost the same as that of pure silica glass. The minimum loss for the proposed composition is estimated to be 0.11 dB/km at 1.55 μm wavelength, and 0.21 dB/km at 1.3 μm wavelength
