Effects of halogen doping on structure of silica glass as a photonic material

Intrinsic loss of optical fibers

“…(4), where n is the refractive index, p the photoelastic coefficient, T f the fictive temperature, and β T the isothermal compressibility [21]. Equation (4) indicates that R d is proportional to T f , as confirmed by the fact that the Rayleigh scattering has a linear relationship with T f in pure silica glasses and fibers, which have only density fluctuation R d [22,23]. We have proposed Eq.…”
