论文摘要
我们研究了在正常分散剂中运行时，在所有纤维谐振器中，在所有纤维谐振器中形成亮和黑暗局部态的影响。在没有拉曼效应的情况下，由于锁定了两个共存连续波状态的域壁，并且经历了一种特定的分叉结构，称为崩溃的蛇。刺激的拉曼散射打破了系统的反射对称性，并修改了域壁的动力学，稳定性和锁定。这种修改会导致形成，不仅是黑暗的，而且还形成了明亮的移动局部状态，否则就没有。我们对这些局部状态进行详细的分叉分析，并将其动力学和稳定性分类为系统的主要参数。
We investigate the influence of the stimulated Raman scattering on the formation of bright and dark localized states in all-fiber resonators subject to a coherent optical injection, when operating in the normal dispersion regime. In the absence of the Raman effect, and far from any modulational instability, localized structures form due to the locking of domain walls connecting two coexisting continuous wave states, and undergo a particular bifurcation structure known as collapsed snaking. The stimulated Raman scattering breaks the reflection symmetry of the system, and modifies the dynamics, stability, and locking of domain walls. This modification leads to the formation of, not only dark, but also bright moving localized states, which otherwise are absent. We perform a detailed bifurcation analysis of these localized states, and classify their dynamics and stability as a function of the main parameters of the system.
