In this talk, we present a method for transmission stabilization and robust dynamic switching for colliding soliton sequences in perturbed broadband waveguide systems. We show that dynamics of soliton amplitudes in N-sequence transmission can be described by N-dimensional Lotka-Volterra (LV) models, where the form of the LV model depends on the nature of the perturbation term. We study the stability and bifurcation analysis of the equilibrium points to stabilize soliton-sequence propagation and to achieve the transmission switching of the soliton sequences.

As optical fiber communications and fiber lasers approach fundamental limits, interest in multimode fibers has grown. Optical fibers designed to support multiple transverse modes offer opportunities to study wave propagation in a setting that is intermediate between single-mode fiber and free-space propagation. A variety of qualitatively-new phenomena have been observed recently in multimode fibers.
