Abstract

In this work we have developed the theory required for a nonlinear FDTD simulator, including the propagator, the implementation of the nonlinearity, boundary and stability conditions, and source get eration. We validated the simulator by reproducing the published results for a self-guiding structure [1] and for a nonlinear directional coupler [2]. We then demonstrate the operation of a rudimentary soliton coupler.
