This work contained a study of the supercontinum generation phenomena in photonic crystal fibers and its appearance and continuity in the fibers depending on the photonic crystal parameters, it was based on general nonlinear Schrodinger equation (GNLSE) and nonlinear Schrodinger equation (NLSE) solving by using the Split-Step Fourier method (SSFM) by Math Lab System, were studied numerically using the Finite Differences in Frequency Domain (FDFD) technique, and shows that the supercontinuum dynamics depends on the pulse power, temporal width, order of soliton, nonlinearity, and its dispersion effect.
