Dispersion Properties of Up-doping Photonic Crystal Fibers

In this papers the novel photonic crystal fibers (PCFs) which consist of air holes surrounded by other substances with triangular lattice arrangement have been assumed. A Full-vector plane wave expansion method (FV-PWEM) has been implemented to calculate the dispersion properties of PCF which possess circular air holes with hole radius , lattice constant , and air filling fraction . Then the effect of up-doping has been studied using two different germanium dioxide percentages. As a result, a tuning of the total dispersion curve has been obtained.
