Hello, i am working on pulse propagation in optical fiber. i have to simulate the nonlinear Schrodinger equation using the FDTD (Finite Difference Time Domain) method. The Schrodinger equation has the form dA/dz = i/2 β2 d2A/dt2 –α/2 +iγ |A2|A where β2 is dispersion, α is attenuation and γ is fiber non-linearity. I need to do this in MATLAB. Please help me in simulation or send me a MATLAB code related to it.
