A fiber analogue of the optical event horizon is proposed via an Airy-soliton collision. The characteristics of an Airy pulse are demonstrated in a photonic crystal fiber. The robust Airy wave packet is capable of being manipulated by a strong soliton in the frame of the Airy-soliton horizon, leading to various distinctive interaction scenarios. The Airy pulse realizes the temporal reversing and still maintains its features even after undergoing a complete wavelength conversion process. Different comb-like spectra are created in the presence of Raman effect by changing the duration of the Airy pulse. The rebounds of Airy pulse in a twin-soliton trapping process is investigated. Meanwhile, a "maximally compressed" Akhmediev Breather is employed to collide with a soliton to compare with the Airy-soliton horizon case. The result can be found in the potential applications of pulse reshaping and temporal-spectral imaging for optical communication and signal processing.
通过艾里孤子碰撞提出了光学事件视界的光纤类似物。在光子晶体光纤中展示了艾里脉冲的特性。在艾里孤子视界框架下，强健的艾里波包能够被强孤子操纵，从而导致各种独特的相互作用场景。艾里脉冲实现了时间反转，并且即使在经历完整的波长转换过程后仍能保持其特征。通过改变艾里脉冲的持续时间，在拉曼效应存在的情况下产生了不同的梳状光谱。研究了艾里脉冲在双孤子俘获过程中的反弹。同时，采用“最大压缩”的阿赫梅迪耶夫呼吸子与孤子碰撞，以与艾里孤子视界情况进行比较。该结果可用于光通信和信号处理中脉冲整形和时间光谱成像的潜在应用。
