【摘要】 对不同光纤色散系数、任意光纤条数、任意长度组成的多级联光传输系统,推导了由自相位调制引起的光功率传递函数,并对此进行了仿真计算。结果表明,自相位调制引起的功率变化与系统的光纤损耗、色散系数、非线性系数、调制频率等参数有关,并且随调制频率增加成波动性变化,从而证明了理论分析的正确性。

【Abstract】 The self-phase modulation induced optical power transfer function is analyzed in cascaded optical fiber communication system in terms of different chromatic dispersion, arbitrary fiber numbers and lengths. Computer simulations are also done. The results of simulations show that the power change of self-phase modulation (SPM) relates to fiber loss, nonlinear coefficient and modulation frequency of system and fluctuates with change of modulation frequency. The simulations are well accordance with the analytical result.
