Dark soliton dynamics and interactions in dynamically photo-induced lattices: interaction with a continuous wave

The dynamics of dark spatial soliton beams and their interactions under the presence of a continuous wave (CW), which dynamically induces a photonic lattice, are investigated. It is shown that appropriate selections of the characteristic parameters of the CW result in different soliton propagation and interaction scenarios, suggesting a reconfigurable soliton control mechanism. Our analytical approach, based on the variational perturbation method, provides a dynamical system for the dark soliton evolution parameters. Analytical results are shown in good agreement with direct numerical simulations.
