Abstract :
We present a comparative assessment of time-domain approaches for modelling nonlinear optical propagation, focussing on a finite-difference time-domain beam propagation method (TD-BPM) and the rigorous transmission line modelling (TLM) method. The assessment is carried out on the basis of reflection and transmission of non-stationary light beams propagating through the junction of linear and nonlinear waveguides.
