We implemented model based on two coupled nonlinear Schrödinger equations that include both the Raman and the Kerr nonlinearities. We used it to study evolution of nonlinear phenomena in the temporal and spectral domains in optical fibers exhibiting high and low birefringence.

Soliton trapping and orthogonal Raman scattering
Run test script to generate above figure and reproduce the manuscript results:
python draw_soliton_traping.py
Note that we also provided script tu run simulations (run_soliton_traping.py
),
however used input data is not publicly available at this time,
but may be obtained from the authors upon reasonable request.

Modulation instability in highly birefringent fibers
To run example of vector modulation instability in highly birefringent fibers with circularly polarized modes in the normal dispersion regime type:
python run_modulation_instability.py
Note that using also raman_polarisation and setting solver.fr to 0 one can simulate the case of low-birefringent fibers.
