How Does the Raman Effect Impact SSFM in Nonlinear Fiber Optics?

[eahaidar]

Hello everyone
I am doing my own split step Fourier method (SSFM)code on Matlab to solve the Nonlinear Schrödinger equation in nonlinear fiber optics
My problem is that in the Nonlinear operator we just multiply it with the initial pulse during SSFM without doing any Fourier transform not like in dispersion since in dispersion it depends on time but if Raman effect which is non linear effect exists and depends on time then what should I do ? Should I do Fourier or not
Thank you for your time

The Split Step method is not the best for Raman scattering - try Marcuse.

What is Marcuse??
