Brillouin gain spectra in singlemode optical fibers, A and B, with GeO2-doped core/pure-silica cladding and pure-silica core/F-doped cladding, are measured at temperatures ranging from -40 to +60†C at a wavelength of 1.32 μm. The temperature coefficients of Brillouin frequency shift were found to be 1.17 and 1.33 MHz / †C for fibers A and B, respectively. Temperature coefficients of Brillouin gain bandwidth were found to be -0.12 and -0.10 MHz / †C. These measurements provide useful information for applications of stimulated Brillouin scattering.
