John Wiley & Sons, Inc.
Based on the ¨ariational approach, a new Hamiltonian
formulation to analyze dispersion-managed solitons in wa¨elengthdi
¨ision multiplexed systems is de¨eloped. Using the Hamiltonian dynamics,
the periodic dispersion maps that minimize residual frequency shifts
in a two-channel system can be easily determined. Comparison with full
numerical simulations ensures the accuracy of our reduced formulation.
