This BeamLab demo calculates the dispersion characteristics of a step-index fiber with circular core. The scanning parameter can be either the normalized frequency V or the wavelength λ. Various dispersion curves can be plotted showing the normalized propagation constant, effective refractive index, mode field diameter and effective mode area as a function of the normalized frequency or wavelength.
