This paper discusses several optimum designs for high birefringence and dispersion compensation in Photonic Crystal Fiber (PCF) for broadband compensation covering the E, S, C, L bands wavelength ranging from (1360 to 1640 nm). The finite element method (FEM) with perfectly matched layer (PML) is generally used to investigate the guiding property. Large negative dispersion over wideband range is obtained in many modified structures with varying dispersion coefficient and with relative dispersion slope (RDS) matched to that of single mode fiber (SMF) of about 0.0036 nm-1 at 1550nm. High birefringence of order 10-2 is observed in most cases with asymmetric structures. In addition to this other properties of PCF like effective area, non-linearity, residual dispersion, and confinement loss are also reported and discussed. © 2006-2016 Asian Research Publishing Network (ARPN).
