✦ Synopsis

An explicit and stable time-domain method that sol¨es the propagation of wa¨e en¨elopes in optical structures is proposed. Based on the Dufort᎐Frankel method and ¨ariable 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 diffusi¨e

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 wa¨eguides. The coupled nonlinear wa¨e equations ha¨e been deri¨ed and discretized using the explicit finite-differenc
