Full-Vectorial Analysis of Photonic Crystal Fibers using a Compact Two-Dimensional Finite-Difference Time-Domain Method

摘要

A full-vectorial analysis of photonic crystal fibers based on a compact two-dimensional finite-difference time-domain method (C2D-FDTD) is presented. The model with material dispersion incorporation is formulated and validated. The Sellmeier equation is implicitly included into the model to account for the material dispersion of silica. In this paper we use a formulation of Maxwell's curl equations by electric flux density and magnetic field intensity, with auxiliary differential equations; and we demonstrate the flexibility and robustness of this approach in treating general material in PCF. We have good agreement with multipole method.
