## Abstract A wide‐band finite‐difference–time‐domain beam propagation method (FD TD‐BPM) based on Padé approximants is introduced to improve the bandwidth of the conventional TD‐BPM. Numerical dispersion relations for the TD‐BPM are derived to demonstrate the increase in bandwidth of the wide‐band

Abstract
In this paper a new semivectorial finite‐difference beam‐propagation method (FD‐BPM) technique for the analysis of nonlinear optical devices is presented. The proposed technique relies on the application of the Runge–Kutta method to perform each propagation step; it is easier to use than the Crank–Nicholson‐based FDBPM method and exhibits better numerical performance. © 2004 Wiley Periodicals, Inc.

In this work, we show the implementation of two explicit three-dimensional finite-difference beam propagation methods (BPM) on two different parallel computers, namely a transputer array and a Connection Machine (CM). To assess the performance of using parallel computers, serial computer codes of th
In this paper, we present a formulation of a finite-difference vector beam propagation method for an isotropic open chiral slab waveguide. This method allows the analysis of wave propagation on a chiral slab waveguide whose structure varies along the propagating direction. Numerical results show tha
Periodic microbend losses in single-mode optical fibers are modeled here Ž . by using the finite difference beam propagation method FD-BPM . To reduce computational demands, the sinusoidal microbending deformation is approximated as a series of constant curvature bends of alternating sign. The spect
We in¨estigate the numerical instability of a finitedifference beam-propagation formulation applied to tapered optical wa¨eguides, and we find that instability may occur with the use of con¨entional transparent boundary conditions. We suggest modified transparent boundary conditions to remo¨e the in
