HAMILTONIAN-DYNAMICS OF DISPERSION-MANAGED BREATHERS

An analytic description is presented for the pulse dynamics in a dispe rsion-managed communications system in which the average dispersion is in the anomalous regime. A variational formalism reduces the governin g equations to a planar Hamiltonian system for which a geometrical int erpretation of the pulse dynamics is given. The reduced model gives a simple method for calculating the ideal enhanced initial power for a d ispersion-managed breather and further exhibits a long-time periodic b ehavior, which is present in the full governing equations. Extensive n umerical simulations verify the range of validity of the reduced equat ions. (C) 1998 Optical Society of America.
