  is there any method to change propagation constant beta0 of optical fiber in optisystem ? as i know that the propagation constant(phase constant) value equals to (2*pi*refractive index / wavelength ) but i didn’t find any parameter that change propagation constant or refractive index in the optical fiber component .

  Good day is so you check the “frequency domain param”

  i see that but these parameters control the dispersion in optical fiber , i asked about the linear refractive index of the fiber can be changed in this component or not !!!

    You can change these options by using the Measured-Index Multimode fiber component or the parabolic one. Both of these components are in the Spatial Library.
