Abstract

An extended finite-difference time-domain (FDTD) method with inclusion of material dispersion for the full-vectorial analysis of photonic crystal fibers (PCFs) is presented in this paper. In order for this extended FDTD method to obtain a fast convergence and high accuracy, a constitutive-parameter averaging technique is employed. Numerical results for a typical PCF verify the validity of the extended FDTD method. With this FDTD mode solver, a new birefringent PCF is also investigated, and interesting results are obtained in this paper.
