We demonstrate in an optical fiber that third-order dispersion yields an unexpected symmetry-breaking dynamics of the modulational instability spectrum. It is found in particular that this spectral asymmetry does not smoothly and monotonically increase when approaching the zero-dispersion wavelength. Instead, it exhibits several local extrema and it can even be reversed at a particular dispersion value. We interpret this behavior as resulting from interactions between dispersive waves and solitons generated from modulation instability.
我们在光纤中证明了三阶色散会导致调制不稳定性谱的意外对称破缺动力学。特别发现，当接近零色散波长时，这种光谱不对称性不会平滑且单调地增加。相反，它会表现出几个局部极值，甚至在特定的色散值处可以反转。我们将这种行为解释为源自色散波和调制不稳定性产生的孤子之间的相互作用。
