An explicit and stable time‐domain method that solves the propagation of wave envelopes in optical structures is proposed. Based on the Dufort‐Frankel method and variable change, it is an explicit difference approach. The method requires less memory and CPU time and is applied to the propagation of a 500‐fs pulse in a diffusive waveguide and in planar waveguides over 2 mm. Transient behavior of the pulse and the effects of waveguide parameters are given. © 1997 John Wiley & Sons, Inc. Microwave Opt Technol Lett 14: 249–252, 1997.
