| 摘 要： | 提出了一种基于阶梯状非线性光纤的脉冲压缩方法.阶梯状非线性光纤包括普通单模光纤,色散位移光纤和高非线性光纤.数值模拟中所使用的所有元件均在现实中存在,并且与其他脉冲压缩方法相比,此方法成本低且易于控制.数值模拟表明:12.5 ps脉宽,300 mW峰值功率的双曲正割脉冲可被压缩至1.28 ps脉宽,1.3 W峰值功率的脉冲.

| Abstract: | A novel optical soliton compression technique based on step-like nonlinearity profiled fiber is proposed.The step-like nonlinearity profiled fiber is composed of single mode fiber(SMF),dispersion-shifted fiber(DSF)and high nonlinear fiber(HNLF).All the components used in the simulation are available in reality.Compared with other soliton compression techniques,this method is easy to control and its cost is low also.It is shown in numerical simulation that a hyperbolic secant pulse,whose width is 12.5 ps and... |
