报道了在被动锁模光纤激光器中形成的矢量孤子的两偏振分量之间存在四波混频的实验证据。首次观察到偏振分辨孤子谱之间存在着位相异相强度变化的额外谱边带，这是由两个孤子极化分量之间的能量交换引起的。对四波混频光谱边带和孤子内部四波混频的其他特性也进行了实验研究和数值验证。
We report on the experimental evidence of four wave mixing (FWM) between the two polarization components of a vector soliton formed in a passively mode-locked fiber laser. Extra spectral sidebands with out-of-phase intensity variation between the polarization resolved soliton spectra was firstly observed, which was identified to be caused by the energy exchange between the two soliton polarization components. Other features of the FWM spectral sidebands and the soliton internal FWM were also experimentally investigated and numerically confirmed.
