Control of soliton interaction in a coherently excited three-level system embedded in a nonlinear waveguide

We have investigated the interaction between a pair of solitons that originate from the breakup of a high-order soliton propagating through a cylindrical waveguide in the presence of three-level resonance associated with a dopant. We found that one can control the nature of this interaction by varying the initial intensity ratio and the overlap between the pump and the signal from which the pair originated.
