TItle: Chaotic dynamics of modulational instability in optical fibers
Abstract: The long distance dynamics of modulational
instability in optical
fibers is studied. A perturbed nonlinear Schrodinger equation which
includes higher order dispersive and nonlinear terms as well as
damping is investigated. When damping is significant, amplifiers are
used to compensate for the fiber losses. Periodically modulated cw
waves are shown to evolve chaotically for a variety of physical
parameters. A nonlinear spectral analysis of the data shows that
the chaotic evolution is characterized by homoclinic transitions in
the spectrum.
