## Abstract Secondβorder nonlinearity in optical media acts as a source for harmonics generation. We set up a timeβdomain model that accounts not only for the second harmonic, but also for the higher harmonics that are induced by a beam propagation. The model is solved numerically using a secondβor
have permitted an accurate fit of the experimental results. It is worth noting that this model permits us to calculate closed expressions that describe the effect on SCM system performance due to important noise sources, such as intermodulaw x tion distortion due to external modulator nonlinearities
A new beam propagation method based on the finite element method (FE-BPM) has been developed for the analysis of nonlinear optical waveguides. A formulation for the FE-BPM that is applicable not only to the TE mode but also to the TM mode is presented. Various techniques for enhancing the performanc
