Effect of the third-order filter term on soliton interactions in soliton transmission systems with filters

The effect of the third-order filter term on soliton interactions in optical fibers with guiding filters is theoretically analyzed.We find that this term causes a significant difference to the interaction of solitons through filters among the regimes of without sliding, with up-and down-sliding frequencies of filters.It is shown that the interaction between solitons can be more effectively suppressed by up-sliding filters than that by down-sliding filters in the presence of the third-order filter term.Moreover, the third-order filter term is found to play a positive role in suppressing soliton interactions in the case of non-sliding.
