论文摘要
由于分散体之间的相互作用,非线性和部分连贯性,因此在光纤系统中的随机功率波动。信号脉冲的功率波动的分析表达,由于其干扰了由部分相干源激发的光纤系统中信号脉冲的非线性相互作用而产生的回声脉冲。分析结果表明,随着源的相干时间降低与我们的数值模拟一致的,平均非线性失真会减小。
Stochastic power fluctuation in a fiber optic system due to the interplay among dispersion, nonlinearity and partial coherence of the source is investigated. An analytical expression for the power fluctuation of a signal pulse due to its interference with an echo pulse generated due to the nonlinear interaction of signal pulses in a fiber optic system excited by a partially coherent source is obtained. The analytical results show that the mean nonlinear distortion decreases as the coherence time of the source reduces consistent with our numerical simulations.
