Dataset for "Raman solitons in waveguides with simultaneous quadratic and Kerr nonlinearities"



The dataset includes data for predictions and simulations of two-component Raman soliton propagation in Lithium Niobate nano-waveguides. Examples of frequency shift and resulting acceleration of solitons under both anomalous and normal dispersion are given each for both quadratic and cascaded Kerr soliton regimes. We provide similar data for cases of soliton collapse in both anomalous and normal dispersion. Predictions were made by treating the Raman response as a perturbation to the soliton. Simulations were done using the Split-Step Fourier method.

We also include modelled Raman response spectrum data for Lithium Niobate and silica.

Shifts in peak frequency of each soliton component are given as a function inverse soliton velocity and soliton propagation constant, calculated by Newton-Raphson method.

Data for soliton frequency shift as a function of soliton peak power is given for both Kerr and two-component solitons. These data were calculated using the semi-analytical perturbation method.
