调制不稳定性（MI）是聚焦非线性介质中普遍存在的现象，并且包括恒定背景对长波长扰动的不稳定性[1，2]。MI的线性阶段的特征在于落在傅立叶光谱的长波长区域中的所有扰动的指数增长[1]。然而，当扰动的幅度变得与背景相当时，即在MI的非线性阶段，这个简单的图片就不再有效了。
Modulational instability (MI) is a ubiquitous phenomenon in focusing nonlinear media, and consists in the instability of a constant background to long-wavelength perturbations [1, 2]. The linear stage of MI is characterized by an exponential growth of all the perturbations falling in the long-wavelength region of the Fourier spectrum [1]. This simple picture ceases however to be valid when the amplitude of the perturbation becomes comparable to the background, ie in the nonlinear stage of MI.
