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