摘要
通过分析旋光纤喇曼放大器中信号光、抽运光的非线性薛定谔波动方程及放大自发辐射噪音特性,提出一种能同时在旋光纤喇曼放大器中产生预计波形放大自发辐射噪音,又方便计算的方法.根据放大自发辐射噪音时域特性,建立并在波动方程中加入放大自发辐射非高斯噪音模型.在考虑旋光纤双折射的非线性效应同时,通过分步傅里叶法对波动方程求解,计算了旋光纤喇曼放大器中的放大自发辐射噪音,并与实验结果吻合.
Abstract
A method both convenience for generation and calculation for anticipated ASE waveform in spun fiber Raman amplifier,by analyzing the NLSE of signal and pump wave in fiber,is proposed.According to its time domain characters,a non-Gaussian noise ASE model is established and the term is added to the NLSE simultaneously by considering birefringence rotation effect in spun fiber Raman amplifier.By solving the equation with Split Step Fourier Method,ASE in spun fiber Raman amplifier is investigated.Numerical results for the ASE noise power spectrum are validated.
