## 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
