We analyze the transverse instability of two-component spatial solitons in a saturable nonlinear medium, in relation to recent experimental observations of spatial vector solitons in photorefractive media. We present the stability analysis for all three realizations: dark-bright, bright-bright, and dark-dark soliton pairs, and demonstrate that both the nonlinearity saturation and incoherent mode interaction can lead to a strong suppression of the soliton transverse instabilities.
我们结合最近在光折变介质中对空间矢量孤子的实验观测，分析了饱和非线性介质中双组分空间孤子的横向不稳定性。我们给出了所有三种孤子对（暗-亮、亮-亮和暗-暗孤子对）的稳定性分析，并证明非线性饱和与非相干模式相互作用均可导致对孤子横向不稳定性的强烈抑制。
