Full-vectorial multimode nonlinear simulations on a real-space Fourier – Gauss grid

A numerical approach for nonlinear propagation in multimode waveguides based on real-space integration of the nonlinear polarization is developed for full-vectorial simulations. The real-space integrations are performed on a Fourier – Gauss quadrature grid in accordance with an earlier scalar ...
