• Zero dispersion wavelength
• Fiber characterization
• Photonic crystal fibers

Here we propose a simple design for a photonic crystal fiber using the golden ratio parameter of pitch and four rings with hexagonal structure of air holes with solid core of silica. By varying the ratio of air hole diameters inside the structure we can control the range of flattened dispersion in anomalous or normal dispersion regime close to zero dispersion wavelength (ZDW). The wide range of wavelengths of 1.19-1.83 mu m with small losses for chromatic dispersion of -0.34 +/- 0.66 ps/(nm-km) and 1.292-1.555 mu m with chromatic dispersion of 0 +/- 0.06138 ps/(nm-km), can allow the possibility of use in different engineering areas, such as supercontinuum generation, pulse reshaping, and dense-WDM (DWDM) based optical communication systems.
