## 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 tha
