拟正态模式 (QNM) 对于理解开放系统的稳定性和共振至关重要，在黑洞物理学中的地位日益突出。我们在这里提出了第一个关于光势 QNM 的研究。我们证明孤子可以支持 QNM，推导孤子微扰方程并给出光纤孤子 QNM 的精确解析表达式。我们讨论了这个本质色散系统中的边界条件，并确定了新的色散特征。从这里，我们发现了与黑洞的新类比，并描述了一种机制，其中孤子是光环现象的强大黑洞模拟器。我们的研究结果具有广泛的应用前景，从用 QNM 描述光脉冲传播，到使用最先进的光纤技术来解决黑洞物理中的问题，例如 QNM 光谱不稳定性和非线性在振铃中的作用。
Quasinormal modes (QNMs) are essential for understanding the stability and resonances of open systems, with increasing prominence in black hole physics. We present here the first study of QNMs of optical potentials. We show that solitons can support QNMs, deriving a soliton perturbation equation and giving exact analytical expressions for the QNMs of fiber solitons. We discuss the boundary conditions in this intrinsically dispersive system and identify novel signatures of dispersion. From here, we discover a new analogy with black holes and describe a regime in which the soliton is a robust black hole simulator for light-ring phenomena. Our results invite a range of applications, from the description of optical pulse propagation with QNMs to the use of state-of-the-art technology from fiber optics to address questions in black hole physics, such as QNM spectral instabilities and the role of nonlinearities in ringdown.
