Abstract

We investigate the propagation dynamics of Airy pulses in pure-quartic dispersion media both numerically and analytically. For linear propagation, our results show that Airy pulses will keep the acceleration-free propagation behaviors under the action of pure-quartic dispersion, quite different from the case in the presence of only quadratic or cubic dispersion. Another notable observation is that the optical fields will evolve to become a symmetric-shaped pulse and the oscillatory tail is gradually suppressed over long propagation. For nonlinear propagation, the Airy pulse having high powers will be shed into multiple soliton dynamics through the physical balance between anomalous pure-quartic dispersion and the Kerr nonlinear effect.

纯四次色散介质中Airy脉冲的无加速传播
本文用数值方法和解析方法研究了Airy脉冲在纯四次色散介质中的传播动力学。对于线性传播,我们的研究结果表明,在纯四次色散作用下,Airy脉冲将保持无加速度的传播行为,与仅存在二次或三次色散的情况有很大不同。另一个值得注意的观察是,光场将演变成一个对称形状的脉冲,振荡尾在长传播过程中逐渐被抑制。在非线性传播中,高功率的Airy脉冲通过反常纯四次色散和克尔非线性效应之间的物理平衡,进入多孤子动力学。
