| 摘 要： | 基于马赫-曾德尔干涉仪(MZI)结构,在Matlab软件中,利用优化的迭代算法、Least Pth-norm算法和AMPSO算法,提出一种用于平坦掺Er光纤(EDF)放大自发辐射(ASE)光源增益谱的级联MZI型全光纤滤波器的优化设计方法,并进行了实验研究。结果表明:采用该方法设计的级联MZI型全光纤滤波器可以有效改善ASE宽带光源输出光谱的平坦度,被平坦波段(1525～1540nm)范围内输出光谱的不平坦度小于±0.73dB,整个C波段光谱3dB带宽为36.344nm。

| Abstract: | By using iterative algorithm,Least Pth-norm algorithm and AMPSO algorithm in the Matlab environment,an optimal method is presented to design the gain flattening filter based on cascaded Mach-Zehnder Interferometer(MZI),and the method is applied to design the filter for flattening ASE source.An example is given to verify that the designed optical filter can effectively improve the flatness of ASE source,the flatness of the flattened spectrum (1 525 nm-1 540 nm) can reach ±0.73 dB,the 3 dB bandwid... |
