%X 根据三束光注入高非线性光纤所发生的四波混频(FWM)过程，分析了基于FWM的多波长全光再生方案中串扰的主要来源。提出了一种新的基于简并四波混频的双波长全光幅度整形方案，连续辅助光的偏振方向与两路偏振正交的高功率数据光偏振方向呈45？夹角。仿真研究表明，通过优化高非线性光纤的双折射值，非简并四波混频串扰可以得到较好的抑制，再生信号的消光比和Q因子均有大幅度提升。<br />
According to the four wave mixing (FWM) process of three input light beams in highly nonlinear fiber (HNLF), the major crosstalk factors occurring in the FWM-based multi-wavelength all-optical regenerators are ana- lyzed. A new two-channel all-optical reshaping scheme based on degenerate FWM is proposed, in which the linear po- larization states of two high-power data light are orthogonal each other and are controlled at 45？ relative to that of con- tinuous wave. It is shown by simulation that the non-degenerate FWM crosstalk components can be greatly suppressed by optimizing the HNLF birefringence and both the extinction ratio and Q-factor of regenerated signal are improved to a great extent.
