| 摘 要： | 运用分裂步长傅立叶方法数值模拟耦合非线性薛定谔方程,研究了双折射光纤中光孤子全光开关的性质.研究发现通过改变初始脉冲输入条件和双折射光纤参数可以实现光孤子全光开关的开和关,同时研究了3阶色散对双折射光纤中光孤子全光开关的影响,得出较大的3阶色散能够破坏光孤子的稳定性,进而对光孤子全光开关产生影响,而较小的3阶色散不会改变光孤子全光开关的性质.

| Abstract: | Simulating the coupled nonlinear Schrodinger equation by using the split-step Fourier method,the properties of optical soliton switch made by birefringent fiber is invest tigated It is found that turn on and turn off of optical soliton switch can be achieved by changing initial soliton condition and fiber parameters.In addition,the effect of third-order dispersion on optical soliton switch made by birefringent fiber is studied Extensive simulations reveal that high third-order dispersion can influence the o... |
