Abstract—In this paper, we demonstrate a new & simple rectangular photonic crystal fiber (RPCF) for high negative dispersion covering the E to U communication band with ultra-high birefringence, large nonlinearity. According to the simulation results, the designed fiber shows negative dispersion coefficient of ‒776 to ‒1591 ps/(nm.km) over E to L communication bands with the relative dispersion slope (RDS) is perfectly matched to that of a single mode fiber. In addition, the proposed RPCF offers a high value of birefringence 2.97×10-2 and a large nonlinear coefficient of 44.5W-1km-1, both at the operating wavelength of 1550 nm. Moreover, the proposed RPCF achieved two zero-dispersion wavelengths in the visible and near IR regions for both of the x and y polarization modes.
