Paper Abstract

We present the results of numerical analysis showing that high geometrical birefringence can be obtained in large mode area photonic crystal fibers. Simulations were carried out using Finite Element Method with Perfectly Matched Layer boundary conditions. To induce possibly high phase modal birefringence, we introduced a few small holes into the central region of the core, which breaks its hexagonal symmetry. Such modification of the fiber geometry is additionally responsible for increasing the effective area of the guided mode. For the optimized fiber design with a pitch distance Λ = 8.8 μm, the phase birefringence reaches B = 1.0×10-4 at wavelength λ = 1.3 μm and B = 1.5×10-4 at λ = 1.5 μm. In addition to high modal birefringence, an important advantage of the proposed fiber design is a single mode operation for wavelength greater than 1.3 μm.
