多泵浦宽带拉曼光纤放大器优化设计的研究

文章以多泵浦拉曼光纤放大器的增益平坦度为切入点,分析了影响多泵浦FRA的增益平坦性的因素,罗列了几种不同的优化算法并着重介绍了遗传算法.研究表明,使用遗传算法优化宽带拉曼放大器是可行的.另外,使用的泵浦个数越多,所得平坦增益带宽越宽.但是,泵浦个数越多,成本也越高,计算量也越大.因此,我们要根据具体要求,选择合适的泵浦...

Research on the Optimal Algorithm for Multi-pumped Fiber Raman Amplifiers

Through the research on gain flatness of multi-pumped fiber Raman amplifiers(FRA) the factors affecting gain flatness of multi-pumped FRA are analyzed,and various optimization algorithms,especially the genetic algorithm,are introduced.The research result indicates that using genetic algorithm to optimize broadband FRA is feasible.In addition,the more the pumps are used,the better the gain flatness of multi-pumped FRA is.But with the increasing of pump number,the cost is increasing too.And it will also add t...
