摘要:

本文研究了具有单个零色散和零非线性点的波导中非相干耦合双频脉冲复合。在这样的波导中,由负非线性支持,孤子动力学甚至可以在正常色散的域中获得。我们演示了孤立波阱对弱脉冲的捕获,形成非线性光子学亚原子和类分子束缚态的脉冲。我们研究了拉曼效应对这些脉冲化合物的影响,发现根据精确的子脉冲结构,它们会减速、加速或完全不受影响。我们的研究结果扩展了系统的范围,在该系统中,两个频率的脉冲化合物可以预期存在,并展示进一步的独特和意想不到的行为。

英文摘要:

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.
