In optical fiber properties in optisystem,under numerical options there is one thing propagator type and has two options EXPONENTIAL AND RUNGE-KUTTA. what does it mean?? what is indicated by propogation

      Hi Amit,

      The propagator type describes the numerical approach to implementing the nonlinear operator in the split-step fourier method, which in turn is used to model dispersion and self-phase modulation.

      For more detail I suggest reading the component help for the optical fiber.

      Cheers
