Abstract

Brillouin gain spectra in two 250-m-long single-mode fibers with GeO/sub 2/-doped core/pure-silica cladding (fiber A) and pure-silica core/F-doped cladding (fiber B) were measured at temperatures ranging from -40 to +60 degrees C at a wavelength of 1.32 mu m. The temperature coefficients of Brillouin frequency shift were found to be 1.17 and 1.33 MHz/ degrees C for fibers A and B, respectively. Temperature coefficients of Brillouin gain bandwidth were found to be -0.12 and -0.10 MHz/ degrees C. These measurements provide useful information for applications of stimulated Brillouin scattering.<>
