| Abstract: | In this article, we consider the continuous wave cw propagation through the nonlinear periodic
structure that consists of alternating layers of both positive and negative Kerr coefficients along the
propagation direction. We investigate the modulational instability MI conditions required for the
generation of ultrashort pulses for the nonlinearity management system. We study the occurrence of
MI at the top and bottom edges of the photonic band gap PBG where the forward and backward
propagating waves are strongly coupled because of the presence of the grating structure. We also
study the MI when cw is detuned from the edges of the PBG into the anomalous and normal
dispersion regimes. In addition, we discuss the existence of gap solitons for the nonlinearity management
system in the upper and lower branches of the dispersion curve through the MI gain
spectra. We observe the generation of higher order solitons in the nonlinear periodic structure when
the input power is inc... |
