摘要：

We report a detailed implementation of a 2-D finite element method that is applied to calculate the stimulated Brillouin scattering (SBS) characteristics in highly nonlinear tellurite microstructured fibers. Our analysis is firstly made in four air-holes different tellurite microstructured fibers and compared to silica and chalcogenide fibers. Such fibers have drawn much interest because of their capacity of increasing the SBS gain. A Brillouin gain coefficient, g(B), of 1 10(-10) m/W is found around the acoustic frequency of 8 GHz. Then, we used real scanning electron microscope images of small core highly nonlinear tellurtie fibers and compared the SBS parameters to numerical predicted results. Good agreement is found between the SBS gain coefficients and the frequency shifts.
