Exceptional points are a ubiquitous concept widely present in driven-dissipative coupled systems described by a non-Hermitian Hamiltonian. To date, exceptional points have been extensively examined in the systems supporting only a few optical modes, thereby leaving the observation of collective (multimode) effects outside of the scope of the study. In the present paper, we analyze the role of exceptional points in nonlinear multimode photonics. Specifically, we provide insights into the complex nonlinear dynamics arising in a continuous wave-driven pair of strongly coupled microresonators. Investigating this system, we demonstrate mechanisms of dissipative Kerr soliton formation in two fundamentally different regimes separated by a line of exceptional points. Highlighting the diversity of emergent nonlinear effects, we describe the on-demand generation of single-solitons, perfect soliton crystals and bright-dark soliton pairs on either side of exceptional points.

异常点是一个普遍存在的概念，广泛存在于非厄米哈密顿量所描述的驱动-耗散耦合系统中。迄今为止，已经在仅支持少数光学模式的系统中广泛检查了异常点，从而将集体（多模）效应的观察排除在研究范围之外。在本文中，我们分析了异常点在非线性多模光子学中的作用。具体来说，我们提供了对连续波驱动的一对强耦合微谐振器中出现的复杂非线性动力学的见解。研究这个系统，我们展示了耗散克尔孤子在由一系列异常点分隔的两个根本不同的机制中的形成机制。突出紧急非线性效应的多样性，
