Suppression and enhancement of soliton switching during interaction in periodically twisted birefringent fibers.

Soliton interaction in periodically twisted birefringent optical fibers has been analyzed analytically with reference to soliton switching. For this purpose we construct the exact general two-soliton solution of the associated coupled system and investigate its asymptotic behavior. Using the results of our analytical approach we point out that the interaction can be used as a switch to suppress or to enhance soliton switching dynamics, if one injects a multisoliton as an input pulse in the periodically twisted birefringent fiber.
