| 摘 要： | 分析了两级串联马赫 曾德尔(Mach Zehnder)干涉型奇偶交错滤波器(Interleaver)的透过率函数。理论上采用梯形波近似的方法,利用傅里叶级数展开的方法选取适当的参数,可得到输出波形通带平坦,阻带加宽的滤波器,其输出稳定性和隔离度均得到了提高。通过实验所得的结果与理论相吻合。 |

| Abstract: | The transmission function of the Interleaver consisting of two cascaded unbalanced Mach-Zehnder interferometer is analyzed. Based on the Fourier series digital approximation method and trapezium wave which is utilized to simulate the output waveshape, the optimal parameter of the Interleaver has been studied.This kind of Interleaver has flat pass band and broad cut band, so it's stability and isolation are improved greatly. The Interleaver is also studied in experiment. The theoretical results are consistent with the experimental results. |
| Keywords: | Interleaver DWDM Flat-top Mach-Zehnder interferometer |
