title: Dispersive destabilization of nonlinear light propagation in fiber Bragg gratings: a numerical verification.
abstract: This paper presents some numerical simulations of the full one-dimensional Maxwell-Lorentz equations that describe light propagation in fiber Bragg gratings in order to confirm that the standard nonlinear coupled mode equations fail to predict the weakly nonlinear dynamics of the system when dispersive instabilities come into play, and that, in this case, the correct slow envelope description of the system requires us to consider higher order dispersion effects.
