Abstract

The low-dispersion and low-confinement loss waveguides are used in optical communication systems. The photonic crystal fibers (PCFs) can be used as waveguide. The several advantages of photonic crystal fibers cause to use these waveguides compared to the conventional fibers. In this paper, two structures of PCFs are designed and modeled. In the first design, a hexagonal photonic crystal fiber is presented which has nearly-zero dispersion at 1.55µm and 2.2w-1km-1 nonlinearity. In the improved structure, the dispersion reaches about zero and negative values and the confinement loss is obtained as small as 1×10-10dB/cm. The nonlinearity of the improved structure is also less than 9.31w-1km-1 and the negative dispersion in the wavelengths longer than 1.55 µm is obtained.
