论文摘要

我们研究了具有单个零分散和零非线性点的波导中不连贯的两频脉冲化合物。在这种波导中,受负非线性支持,即使在正常分散域中也可以获得孤子动力学。我们证明了孤立波井捕获弱脉冲,形成非线性 - 光子元原子和脉冲的分子状结合体。我们研究拉曼效应对这些脉冲化合物的影响,发现,根据精确的子孔构型,它们会减速,加速或完全不受影响。我们的结果扩展了可以预期存在两种频率脉冲化合物的系统范围,并展示了进一步的独特和意外行为。

We study incoherently coupled two-frequency pulse compounds in waveguides with single zero-dispersion and zero-nonlinearity points. In such waveguides, supported by a negative nonlinearity, soliton dynamics can be obtained even in domains of normal dispersion. We demonstrate trapping of weak pulses by solitary-wave wells, forming nonlinear-photonics meta-atoms, and molecule-like bound-states of pulses. We study the impact of Raman effect on these pulse compounds, finding that, depending on the precise subpulse configuration, they decelerate, accelerate, or are completely unaffected. Our results extend the range of systems in which two-frequency pulse compounds can be expected to exist and demonstrate further unique and unexpected behavior.
