色散管理孤子的相位噪声

Phase noise of dispersion-managed solitons

Elaine Spiller, Gino Biondini

摘要:

本文对光纤通信和飞秒激光器中色散管理孤子的噪声相位偏差进行了定量研究。我们首先发展了色散管理的非线性薛定谔方程(DMNLSE)的微扰理论,以计算噪声引起的孤子参数的均值和方差。然后,我们使用的分析结果来指导重要性采样的蒙特卡罗模拟的噪声驱动的DMNLSE。这些结果与那些从原来的,未平均的,控制方程的比较确认的DMNLSE作为许多色散管理系统的模型的有效性,并量化的色散管理孤子相对于噪声引起的相位抖动的鲁棒性增加。

英文摘要:

We quantify noise-induced phase deviations of dispersion-managed solitons in optical fiber communications and femtosecond lasers. We first develop a perturbation theory for the dispersion-managed nonlinear Schrodinger equation (DMNLSE) in order to compute the noise-induced mean and variance of the soliton parameters. We then use the analytical results to guide importance-sampled Monte-Carlo simulations of the noise-driven DMNLSE. Comparison of these results with those from the original, un-averaged, governing equations confirm the validity of the DMNLSE as a model for many dispersion-managed systems, and quantify the increased robustness of dispersion-managed solitons with respect to noise-induced phase jitter.
