Modeling of photonic crystal fibers with the Scalar Finite Element Method

摘要

A numerical model based on the scalar finite element method is applied to analyse the dispersion properties of photonic crystal fibers having a solid core and a cladding region with multiple air-holes. A correction which accounts for the polarization effects due to the large refractive index difference between silica materials and air holes is included in the analysis. The obtained numerical results show a good agreement with full-vector ones reported in literature.
