We propose the method of calculation of the dispersion characteristics and field distribution of the modes in straight and bent multi-core microstructured fibers. The method is implemented for the analysis of the birefringence in dual-core microstructured fibers in dependence on the fiber parameters (air hole diameter, hole separation, distance between guiding cores) and bend radius. The term "birefringence" we understand here in the wide sense including both the difference of the parameters of orthogonally polarized modes (polarization birefringence) and the difference of the parameters of two supermodes with identical field distribution propagating in dual-core microstructured fibers (supermode birefringence). The optimization of the parameters of such fibers using as vector bend sensors is considered.
