The theory that optical amplification of stimulated Brillouin scattering can be generated through interaction of two counter propagating laser beams in photonic crystal fiber is used. Varieties of Brillouin scattering spectrum and Brillouin frequency shift along with temperature are studied via experiments. The experiment results show that the photonic crystal fiber has a frequency shift of 9.795 GHz, a Brillouin spectrum width of 19 MHz and a frequency shift temperature coefficient of 1.33℃/MHz when the incident beam has a wavelength of 1 548 nm at temperature 25℃. Brillouin scattering spectrums of a high nonlinear photonic crystal fiber and a standard single-mode fiber are measured and discussed, and results are presented that the photonic crystal fiber has a narrower Brillouin scattering bandwidth and a stronger temperature dependence corresponding to the standard single-mode fiber, and the photonic crystal fiber can turn into a novel fiber sensing component for a distributed fiber Brillouin sensor.
