Hello,

I am working on pulse propagation in optical fiber. pulse propagation in optical fiber is modeled by the Nonlinear Schrodinger Equation. I want to numerically solve the Nonlinear Schrodinger Equation using the FDTD method. NLSE has the general form dA/dz = -β1dA/dt (i/2)β2dA2/dt2 – αA/2 + iγ|A2|A
Where A is pulse envelope, β1 is group velocity, β2 group velocity dispersion, α fiber attenuation and γ is fiber nonlinearity.

Can anyone help me or send me a related MATLAB code for it?
