Analysis of dispersion and confinement loss in photonic crystal fiber

Chromatic dispersion and confinement loss are two significant issues in the design of photonic crystal fiber. This paper presents a systematic study of these two issues for five rings hexagonal photonic crystal fiber along with its dependence on structure and material used. The values of these two propagation characteristics obtained for different refractive indices and hole diameters reveal that optimization of these two characteristics depend on the application requirements, but not for determining which fiber structure is the best. Photonic crystal fiber structure is modeled using OPTI FDTD 8 simulation software and dispersion as well as loss is plotted by MATHCAD 2000i Professional tool.
