Having ignored the effect of loss and third order dispersion coefficients, we found that the interaction distance changes in a quasi-Gaussian manner as a function of two interacting pulse separation. The effects of varying pulse widths and constant pulse separation and the reverse (i.e., the constant pulse widths and varying pulse separation) on the interaction length and the interaction distance have been investigated. It is found that in either case, the interaction distance and interaction length change exponentially with pulse width.]]>Ablowitz, M.J. and P.A. Clarkson,1991Agrawal, G.P.,2001Yang, W.Y., W. Cao, T.
