A Simple Approach of Analyzing the Performance of Erbium-Doped Fiber Amplifiers

掺饵光纤放大器的主要性能是它的饱和增益特性和噪声系数。本文首先用两个经验公式 ,介绍了一种用于模拟掺饵光纤放大器性能的简单方法。接着给出了一个超定方程组 ,对这种方法作了进一步的改进。最后分别给出了利用改进前后的方法计算所得到的结果 ,同时对计算结果和测量数据作了比较 。

The main performances of erbium doped fiber amplifiers are the saturated gain and noise figure. In this paper, a simple approach is introduced to simulate the performance of erbium doped fiber amplifiers by using two empirical formulas. Then conflict equations are presented to improve this approach. At the end of the paper calculation results before and after improvement is given, furthermore the comparison of calculation results and measured data is also given. It has been shown to be more accurate.
