- We derive an analytic expression of the group velocity dispersion ( gvd ) induced chirp and the self - phase modulation ( spm ) induced chirp in the normal dispersionregion of non - kerr - like optical fibers with saturable nonlinarity . the evolution of chirp is simulated by numerical methods . the studied results show that the more powerful saturable effects , the smaller is chirp and the gently is chirp . the net chirp is zero in the central region of the pulse
从理论上推导出具有饱和非线性的非克尔光纤正常色散区内，群速度色散效应导致的啁啾和自相位调制效应导致的啁啾解析表达式.利用数值解法模拟了非克尔光纤正常色散区啁啾演变过程.研究结果表明：当非克尔光纤的饱和非线性增强时，净啁啾不断减小，而且，越来越平缓，脉冲中心附近区域净啁啾接近零 - Using the variational method , analytical conditions for stationary pulse propagation in dense period fibers with strong dispersion management are deduced . the expression of initial soliton peak power is given . by employing the obtained formulas , the soliton evolution semi - analytically in various dispersion maps can be investigated . effects of the third order dispersion are also studied in this paper . the results show that imperfect dispersion slope compensation can cause pulse central position shift and even serious degradation of soliton shape
利用变分方法,推导出了在强色散管理的密集周期光纤中脉冲稳态传输的解析条件,并给出了初始脉冲峰值功率的表达式.运用这些公式,对各种色散管理系统中孤子的演化进行了半解析的考察.三阶色散也被考虑在内.结果表明:不完善的色散斜率补偿将导致脉冲中心位置的偏移甚至严重的孤子形状劣化
