摘要
本文数值分析了脉冲初始啁啾对色散控制孤子传输性能的影响 ,得出的结论为 :适当地选择正的初始啁啾可以提高后补偿系统中孤子的传输特性 ;负啁啾可以提高前补偿系统中孤子的传输性能。初始啁啾参量的大小与色散补偿的结构以及平均输入功率有关 。
In the article, the effects of initial pulse chirps on dispersion-managed soliton transmission systems are discussed by using computer simulation. The main results are: the positive initial chirps enhance the transmission characteristics of the soliton by post-compensation; and the negative initial chirps improve the transmission characteristics of the soliton by pre-compensation. The optimum initial chirps are related to the compensation configurations and input powers. A new method for designing dispersion-managed soliton transmission systems by using pre-chirp technology is given.
