✦ Synopsis

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 the two methods have been implemented and a comparison between the speed of the serial and parallel codes has been made. Large gains in the speed of the parallel FD-BPMs have been obtained compared to the serial implementations. In addition, a comparison between the performance of the transputer array and the CM in executing the two FD-BPMs has been discussed. Finally, to assess and compare the two methods, three different rib waveguides and three different directional couplers have been analysed and the results compared with published results.

## 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
