Controllable interaction of Airy beams via initial launch angle in Kerr media

Abstract

We investigate the anomalous interactions of both in-phase and out-of-phase Airy beams in Kerr media with different intervals and initial launch angles (“velocity”) by means of direct numerical simulation . Interaction between double beams interference and initial launch angle leads to a host of new propagation dynamics of solitons shedding from Airy beams. Unlike the interaction between two Airy beams without initial velocity, where the two in-phase and out-of-phase Airy beams always attract and repel each other, here, both the in-phase and out-phase Airy beams can present attraction or repulsion under proper interval and initial angle condition. Their propagating dynamics depend in a sensitive way on the sign of the interval and initial launch angle.
