Chaotic scattering of solitons on point defects in fiber Bragg gratings.
We present detailed studies on the interaction between solitons and defects in nonlinear Fiber Bragg gratings. The numerical simulations demonstrate that in the case of strong defects the scattering process of slow gap solitons exhibits so-called n-bounce resonance and becomes chaotic. Our results provide a quantitative guideline to experiments on the dynamics of soliton-defect interactions in these systems.
