Abstract :
Brillouin-gain profiles are measured for fused-silica core and GeO 2-doped core fibres at wavelengths of 1286 nm and 1500 nm. The intrinsic Brillouin linewidth is found to vary as the square of optical frequency, as predicted for bulk fused-silica. However, the experimentally evaluated Brillouin linewidths at both wavelengths are broader by a factor of 2.5 than those predicted for the bulk glass
