对单模光纤正群速色散区中基于暗孤子交叉相位调制的亮脉冲压缩进行了定量计算和详细分析。结果表明，亮脉冲的压缩程度与暗孤子相对于亮脉冲的初始峰值功率有关。初始相对峰值功率愈高，亮脉冲的压缩比和压缩后的峰值功率愈高，同时所需的光纤长度愈短。对于给定的初始条件，光纤长度存在一最佳值。在最佳长度处，压缩后的亮脉冲峰值功率最高，宽度最窄。
The bright pulse compression based on dark soliton cross-phase modulation in the positive group velocity dispersion region of single-mode fiber is quantitatively calculated and analyzed in detail. The results show that the degree of compression of the bright pulse is related to the initial peak power of the dark soliton relative to the bright pulse. The higher the initial relative peak power, the higher the compression ratio of the bright pulse and the peak power after compression, and the shorter the required fiber length. For a given initial condition, there is an optimal value for the fiber length. At the optimum length, the peak power of the compressed bright pulse is the highest and the width is the narrowest.
