Abstract
Microstructured optical fibers (MOFs), including Holey and multi-layered fibers have attracted great interest both in applications and theory due to their wide range of novel optical properties particularly adjustable nonlinearity. Up to date, analytical/numerical models have been developed to determine the electromagnetic fields distribution in the transverse directions and for various MOFs. We have developed a general three dimensional (considering cylinderical symmetry) analytical-numerical model of Stimulated Brillouin scattering in MOFs in which both electromagnetic field distribution in the transverse direction and its propagation due to a nonlinear effect (Brillouin scattering) is studied. The model has been employed to describe the Stimulated Brillouin Scattering phenomena in single and multi-mode core-cladding fibers. We examine how the structure of such a fiber like core size, index profile, and the laser wavelength affect the Brillouin profile in single and multi-mode regimes. We refer to a specific application of Brillouin scattering in fibers i.e. Brillouin based fiber optic sensors and specify the parameter space (core size, index profile, wavelength) for optimum sensing capability.
