Abstract The linear time‐domain beam propagation method (TD–BPM) has been extended to model the propagation of pulsed optical beams in second‐order nonlinear optical material of integrated waveguides. The coupled nonlinear wave equations have been derived and discretized using the explicit finite‐difference method. The nonlinear TD–BPM method developed in the present work is very efficient, and is simple to implement. © 2001 John Wiley & Sons, Inc. Microwave Opt Technol Lett 28: 253–257, 2001.
