On the theory of chirped optical soliton in fiber lines with varying dispersion
PACS: 42.65.-k
We study soliton solution of a path-averaged (in the spectral domain) propagation equation governing transmission of a chirped breathing pulse in the fiber lines with dispersion compensation. We demonstrate that the averaged Hamiltonian model correctly describes features of chirped soliton observed in numerical simulations and experiments. We show that the Hamiltonian is bounded from below if the average dispersion is anomalous ((d) > 0) that together with a condition Haoi < 0 indicates stability of dispersion-managed soliton in this region.
