摘要
在分析单模光纤群速度色散(GVD)效应和自相位调制(SPM)效应相互作用的基础上,导出GVD和SPM共同作用引起的啁啾表达式,全面分析了色散长度L_D、非线性长度L_(NL)与啁啾变化的关系。结果表明:随着L_D/L_(NL)的不同,啁啾特性有着显著变化,当N=L_D/L_(NL)=1,即实现了单模光纤中群速度色散效应与非线性效应相互作用所致啁啾的最佳匹配,通过控制脉冲输入功率,可望实现高斯光脉冲无啁啾的稳定传输。
On the basis of GVD and SPM, an analytic expression of chirp induced by the interactions of both SPM and GVD chirp was obtained, completely analyzing the relationship of chirp changes and dispersion length LD and nonlinear length LNL. The results show that the feature of chirp changes obviously with the altering of LD/LNL. The formula N - LD/LNL = 1 means that the chirp has completed the best match of the chirp in a single-mold fiber. The stability of zilch -chirp pulse may be obtained by controlling the input power of Gauss pulse in a fiber.
