heal.abstract	The evolution during propagation of a Pereira-Stenflo type (bright and chirped) solitary pulse subjected to dispersion modulation in a communication line with Er3+-doped fiber amplifiers is investigated on the basis of a variational effective particle model. The model leads to an extended phase plane representation of the dynamics of the pulse and yields the evolution equations for the pulse width and chirp. The associated Poincare surfaces of section provide a useful qualitative and quantitative designing tool for a soliton-based optical link with weak to mildly strong dispersion modulation. The investigation relates the general properties of the evolution to the modulation strength and its spatial periodicity. Both the sinusoidal and the step-wise dispersion modulation schemes are considered. For the sinusoidal, both weak and relatively strong dispersion modulation, it was found that for long periodicity of the modulation (as compared with the periodicity which characterizes the non-modulated breathing of the pulse), chaotic regions on the Poincare surfaces of section are either absent or limited and the pulse preserves its form for adequately long distances for a wide range of choices of its initial parameter values. On the contrary, the higher the modulation strength and/or frequency are the wider the chaotic region gets. For the case of the step-wise dispersion modulation the chaotic behavior sets in for lower values of the frequency of the dispersion modulation, thus, rending the regions for choosing the initial pulse parameters, which are associated with non-destructive propagation of the pulse, narrower.
