Persistent Oscillations of
Scalar and Vector Ddispersion-Managed Solitons
Chaos 10, 539-550 (2000)
Abstract:
We show that both orthogonal and parallel internal modes exist on the
background of a dispersion-managed (DM) soliton in randomly birefringent
fibers. The orthogonal modes exist for arbitrarily small values of the
dispersion map strength, while the parallel modes exist only when the map
strength exceeds a certain threshold value. We demonstrate that initial
perturbations of a DM soliton's profile that consist of one or more
internal modes, exhibit nearly stable oscillations over very long
propagation distances, before decaying into radiation.
