This paper presents a new single mode photonic crystal fiber based on square lattice structure with ultraflattened dispersion and also the two different air-hole diameters in cladding region is proposed. In this article, the dispersion is investigated using a proficient compact two dimensional finite-difference time-domain (2-D FDTD) method and the anisotropic perfectly matched layer (PML) for the boundary treatment. To examine the single properties of PCF like dispersion and other polarizing properties the outcome of variation in wafer dimension of a constant lattice size is analyzed. The elementary characteristics of single mode photonic crystal fibers (SMPCFs) such as chromatic dispersion are numerically investigated and Normalized frequency parameter parameter is also being estimated in this paper. We find that the proposed photonic crystal fibers demonstrate properties of ultraflattened nearly zero dispersion of 0±0.6ps/(km·nm) in wavelength range of 1.3 to 1.6 µm through numerical simulation and optimizing the geometrical parameters.
