ABSTRACT
Soliton propagation direction can be engineered in optical fibers in the presence of high-order effects (HOEs). It is well known that Raman effects can decelerate the soliton. Here we investigate the manipulation of the deceleration or acceleration of soliton emitted from Airy pulse whose spectrum is imposed an initial quadratic phase modulation (QPM) in optical fibers in the absence of HOEs. We show that, under the action of the anomalous second-order dispersion (SOD) and Kerr nonlinearity, Airy pulse with QPM is able to emit soliton with acceleration or deceleration depending on whether the QPM is negative or positive, and at a rate that is determined by the magnitude of QPM. The reason is that the acceleration behaviors of incident Airy pulse is altered depending on whether SOD and QPM have the same or opposite signs. Our study shows the possibility of controlling and manipulating the soliton propagation and interaction in optical fibers without HOEs, by purposely choosing appropriate QPM parameter of an Airy pulse.

Mentions: Under the action of Kerr nonlinearity, the Airy pulse without QPM was distorted in the form of soliton shedding and dispersion background during propagation27. In the above discussion, we only consider the impact of QPM on the linear propagation of Airy pulse and find some new propagation behaviors. Do these unique linear properties make the nonlinear propagation of Airy pulse with QPM different from that of Airy pulse without QPM? Moreover, we move our attention on the nonlinear propagation of Airy pulse with an initial QPM. Figure 5 shows the temporal evolutions of Airy pulse with different values of QPM as a function of propagation distances in the anomalous dispersion regime. When , the soliton is shed from the main lobe of Airy pulse located in the vicinity of and propagates along a straight line (white dash line), indicating its velocity is not changed during propagation2734. This is completely changed in the case of . The main effect of QPM is to shift the shedding soliton peak linearly with propagation distance . The shedding soliton is delayed or advanced depending on whether the sign of is minus or plus. When is positive, the QPM slows down the shedding soliton, and the soliton peak is delayed by an amount that increases linearly with distance. The opposite occurs as is negative. The initial QPM leads to shedding soliton with an enhanced rate of acceleration or deceleration that is determined by the sign and amplitude of . These results can also be applied for the case of spatial Airy beam with QPM. In addition, soliton shedding from Airy beams can also been manipulated at nonlinear interface by rotating the interface with an inclination angle37.
