The nonlinear propagation of ultrashort pulses in nonlinear periodic materials was analyzed in correlation to alternating oppositely-signed Kerr coefficients. Simulation results for the behavior of pulses impinging on periodically nonlinear optical devices were obtained by deriving coupled-mode equations for nonlinear periodic gratings. It was noticed that short-duration pulses had a spectral bandwidth which exceeded the width of the dynamic stopband which they created inside the limiter. This resulted in a non-limited transmission of the power which lies outside the device stopband.
