We present a new perturbative approach to the study of signal-noise interactions in nonlinear optical fibers. The approach is based on the hydrodynamic formulation of the nonlinear Schrödinger equation that governs the propagation of light in the fiber. Our method is discussed in general and is developed in more details for some special cases, namely the small-dispersion regime, the continuous-wave (CW) signal and the solitonic pulse. The accuracy of the approach is numerically tested in the CW case.
我们提出了一种研究非线性光纤中信号 - 噪声相互作用的新微扰方法。该方法基于支配光在光纤中传播的非线性薛定谔方程的流体动力学公式。我们对该方法进行了一般性讨论，并针对一些特殊情况进行了更详细的展开，即小色散 regime、连续波（CW）信号和孤子脉冲。在连续波情况下对该方法的精度进行了数值测试。
