A full vector finite element method has been used to simulate our proposed PCF’s guiding properties and for that purpose, COMSOL MULTYPHYSICS 5.0 is used. To mask the backscattering, a circular perfectly matched layer with a thickness of 1.35 um is incorporated in the design near the outmost ring. By using the equation of 10, refractive index of the GeO2 doped core is calculated. Material dispersion is calculated by using the three-term Sellmier’s formula 11. Our simulation has been carried out using 80% mole GeO2. After solving the eigenvalue problems of Maxwell curl equations to obtain the operative refractive index neff, other parameters like chromatic dispersion (D), fiber nonlinearity (?), birefringence (B) are evaluated using the following well-known equations.A full vector finite element method has been used to simulate our proposed PCF’s guiding properties and for that purpose, COMSOL MULTYPHYSICS 5.0 is used.
