利用高非线性光纤中的交叉相位调制和四波混频分别在仿真中实现了时间透镜. 对基于交叉相位调制的时间透镜中的高非线性光纤中的非线性过程进行了仿真分析. 仿真结果表明, 该时间透镜的主要影响因素为色散、自相位调制与四波混频; 通过采用带有一定色散斜率的高非线性光纤可同时消除色散、自相位调制和四波混频的影响; 另外, 该高非线性光纤的色散零点最好选在信号脉冲和抽运脉冲波长的中心附近. 然后对基于四波混频的时间透镜的实现进行了仿真分析. 仿真结果表明, 该时间透镜的主要影响因素为色散、 自相位调制和其他的四波混频; 通过设定合适大小的信号脉冲和抽运脉冲的功率可消除自相位调制和其他的四波混频的影响; 另外, 通过在高非线性光纤中引入一定的色散可进一步提高信号脉冲和抽运脉冲的功率, 从而获得更高功率的输出脉冲. 最后对两种时间透镜系统做出了比较.Cross phase modulation based time lens and four-wave mixing based time lens are realized by utilizing cross phase modulation effect and four-wave mixing effect in the high nonlinear fiber, respectively. The nonlinear process in the high nonlinear fiber of cross phase modulation based time lens is simulated and analyzed. The simulation and the analysis show that the main influence factors are dispersion, self phase modulation and four-wave mixing, which can be eliminated by using the high nonlinear fiber with a certain amount of dispersion slope. Besides, the zero-dispersion wavelength of the high nonlinear fiber should be around the centre between the signal pulse and pump pulse. Then, the nonlinear process in the high nonlinear fiber of four-wave mixing based time lens is simulated and analyzed. The simulation and the analysis show that the main influence factors are dispersion, self phase modulation and other four-wave mixing, which can be eliminated by using the signal pulse and pump pulse with a certain amount of power. Besides, the powers of the signal pulse and the pump pulse can be improved by using the high non-linear fiber with a certain amount of dispersion, then the power of the output pulse can be improved, too. Finally, two kinds of time lenes are compared with each other.
