An FDTD-based tool for simulation of nonlinear interactions of guided waves
A new tool is proposed for simulation of spatial second-order nonlinear interactions of guided waves based on modified one-dimensional finite-difference time-domain (1-D FDTD) calculations with an embedded nonlinear susceptibility tensor. Parallel 1-D engines are used to calculate three-dimensional behaviors according to propagation properties of the waveguides. The method has been used successfully to simulate difference-frequency mixing in GaAs for terahertz generation, and could be applied to a wide range of problems that could not be solved easily by conventional methods.
