An explicit central difference scheme to implement the beam‐propagation algorithm for analyzing pulse propagation in photonic integrated circuits is discussed. The method has been successfully applied to planar waveguides, channel waveguides, and waveguide couplers. The method shows stability even after long propagation distances and does not involve computation of fast Fourier transform at any step, contrary to the methods discussed earlier. © 1992 John Wiley & Sons, Inc.
