Time-domain modeling of nonlinear pulse propagation with an extended stability spatially filtered FDTD method

Summary form only given, as follows. Nonlinear pulse propagation studies for microwave and photonics applications are known to present large computational load to conventional simulators. Therefore, there is a need for innovating existing algorithms for nonlinear problems, especially FDTD. To this end, a numerical methodology based on a spatially filtered FDTD technique is presented. It is demonstrated that the method is significantly faster than the standard nonlinear FDTD, maintaining its level of accuracy.
