论文摘要
从理论上讲，我们研究了在纯四阶分散点驱动的Kerr腔中局部状态的动力学，分叉结构和稳定性。分析了正常和异常的组速度分散性方案，强调了标准二阶分散案例的主要差异。在异常状态中，单个和多峰局部状态存在，并且在参数空间的一个较宽区域上保持稳定。在正常的分散体状态下，存在稳定的狭窄的明亮孤子。我们的某些发现可以通过这里为空间特征值报道的新场景来理解，这对所有局部状态都施加了振荡的尾巴。用光学信件出版。
We theoretically investigate the dynamics, bifurcation structure and stability of localized states in Kerr cavities driven at the pure fourth-order dispersion point. Both the normal and anomalous group velocity dispersion regimes are analysed, highlighting the main differences with the standard second order dispersion case. In the anomalous regime, single and multi-peak localised states exist and are stable over a much wider region of the parameter space. In the normal dispersion regime, stable narrow bright solitons exist. Some of our findings can be understood by a new scenario reported here for the spatial eigenvalues, which imposes oscillatory tails to all localised states. To be published in Optics Letters.
