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

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.
