Abstract An explicit and stable time-domain method for solving the propagation of wave envelope in optical structures is proposed. Based on Dufort-Frankel method and variable change, it is a explicit difference. The method takes less memory and less time and it is applied to propagation of a 500 fs pulse in a waveguide over 2mm. Transient behavior of the pulse and the effects of the waveguide parameters are given.
