摘 要: 提出一种在单模光纤正常色散区由连续波产生超短光脉冲对的新方法 即让连续波和一个波长位于光纤负色散区的高阶孤子在光纤中同时传输 ,互相位调制效应和群速度色散效应的互相作用能使连续波演化成超短光脉冲对 本文还通过计算机模拟 ,对该方法进行了全面的考察和分析 结果表明 。 A new method for ultrashort optical pulse pair from a CW signal in the normal dispersion regime of optical fibers is suggested. It consists of copropagating a CW signal with a high order soliton at a different frequency in the anomalous regime of an optical fiber. The cross phase modulation imposed by the soliton on the CW signal, can induce the generation of ultrashort pulse pair from the CW signal. Numerical simulations show that the method is effective under realistic practical conditions.
