Abstract :
A simplified model for the effect of Ge doping on the longitudinal acoustic modulus and acoustic damping coefficient of silica fibres is presented. The model provides the longitudinal acoustic velocity, Brillouin spectral width, and Brillouin gain coefficient as a function of the Ge concentration. The model only requires knowledge of high-level, easily-measurable physical properties of the bulk fictive materials. The model and experimental data were found to be in excellent agreement.
