As light travels in the core of an optical fiber, many interesting phenomena are observed like the parametric nonlinearities from the third-order susceptibility composed of Kerr Effect and the Stimulated Raman Scattering. In this report, the Kerr effect in the core of a photonic crystal fiber is examined by using the Z transform. The 2D FDTD is used as numerical technique, and Z transform is applied instead of the Fourier Transform. As the numerical example, the square lattice photonic crystal fiber is considered as simulation structure. We observed only the weak Kerr Effect in the propagation pulse.
