AI总结:

本文通过理论和实验研究,测试了光纤四波混频中光谱不对称不变量的鲁棒性,发现其对微小偏差高度敏感,并表明理想化系统介于非级联四波混频与非线性薛定谔方程系统之间。

摘要:

光谱不对称性的守恒是理想四波混频过程的一个基本特征,该过程存在于结合了二次色散和三阶非线性的介质中。本文在实验配置中测试了这一不变量的鲁棒性,其中光纤的激发条件被顺序更新,模拟无限传播。这项理论和实验研究揭示了不对称性对理想情况微小偏差的高度敏感性,并且我们表明,我们的理想化系统表现为非级联四波混频理想情况与由非线性薛定谔方程控制的系统中传播之间的中间情况。

英文摘要:

The conservation of spectral asymmetry is a fundamental feature of the ideal four-wave mixing process as it exists in a medium combining quadratic chromatic dispersion and third-order nonlinearity. We test in this paper the robustness of this invariant in an experimental configuration where the excitation conditions of an optical fiber are sequentially updated, mimicking infinite propagation. This theoretical and experimental study reveals the high sensitivity of the asymmetry to very slight deviations from the ideal case, and we show that our idealized system behaves as an intermediate case between the ideal case of non-cascaded fourwave mixing and propagation in a system governed by the nonlinear Schr{ö}dinger equation.
