We report a study of the temperature dependence of the Brillouin gain and loss for three different kinds of commercial polarization-maintaining fibers for the first time to our knowledge. The Brillouin frequency differences between the fast and slow axes are independent of the temperature, varying between 2.9 and 4.3 MHz. Using 2-ns pulses (equivalent to a spatial resolution of 20 cm), we find that the temperature coefficients for the relative Brillouin power at a wavelength of 1310 nm are 0.26%/C° (panda fiber), 0.23%/C° (bow-tie fiber), and 0.04%/C° (tiger fiber); the temperature coefficients for the Brillouin frequency are 1.37 MHz/C° (panda), 1.66 MHz/C° (tiger), and 2.30 MHz/C° (bow-tie). The temperature coefficients for the Brillouin gain bandwidth are 0.15 MHz/C° (panda), 0.20 MHz/C° (bow-tie), and 0.22 MHz/C° (tiger).
