Trapping and guiding soliton through Airy pulse

Abstract

We show that Airy soliton interaction in anomalous dispersion and focussing nonlinear regime provides an effective control on the co-propagating sech soliton dynamics. Cross phase modulation (XPM) induced nonlinear phase results varying group velocity of the sech soliton which leads to its temporal shift towards leading edge. The soliton could be made either advanced or delayed by choosing an appropriate initial time delay between the two co-propagating pulses. The effect of the initial time delay on trapping efficiency is also disclosed. Additionally, we have studied the effect of temporal chirp in Airy pulse on sech soliton dynamics. It is found that introduction of positive chirp inhibits the XPM-induced temporal shift of the soliton, while negative chirp boosts the XPM-induced acceleration. Further, the effect of group delay on the trapping and guiding of the soliton has been investigated. Moreover, the role of relative dispersion and nonlinear length on the soliton pulse acceleration are investigated. These results are expected to provide a better understanding on manipulation of light by light that could be useful in all-optical switching and signal control.
