Highly Birefringent Dispersion Compensating Index Guiding Square Photonic Crystal Fiber with Large Nonlinearity for Fiber Optic Transmission System

A square lattice dispersion compensating highly non-linear photonic crystal fiber is presented in this paper. Finite Element Method (FEM) with the perfectly matched layer is used to observe the impact of fiber parameters on birefringence, dispersion, and nonlinearity. The proposed highly birefringent dispersion compensating fiber shows that it is possible to obtain birefringence of $3.2 \times 10^{-2}$ and dispersion of 1501 ps/(nm.km) at 1550nm wavelength by adopting the smallest number of design parameters. The proposed fiber will be an excellent candidate for dispersion compensation in fiber optic transmission system.
