Paper Abstract

We present the results of modeling of photonic crystal fibers with a square lattice and square holes. In photonic fibers having an order m = 2 symmetry the degeneracy of the fundamental mode that is a combination of the polarization modes HE11x and HE11y disappears. The advantage of the square structure is that the photonic crystal fiber becomes very sensitive to deformations caused by external factors yet it remains highly birefringent. The propagation constants of both modes were calculated using the vector method of biorthonormal bases. The use of a square lattice in a photonic crystal fiber makes possible to achieve birefringence of the order of 10-2. We have examined the dependence of birefringence on the geometrical parameters of the fiber's structure.
