New class of periodical nonlinear waves in single-mode fiber near the zero group-velocity dispersion spectral point

摘要

We report new class of steady-state periodic solutions of the nonlinear Schroedinger equation perturbed by the cubic dispersion term and present their basic properties including the existence areas. Possibility of formation of periodic pulse trains with high contrast and high repetition rates in the spectral region close to the point of zero group-velocity dispersion is demonstrated.
