摘要
本文首次用干涉法对反射式的 Mach- Zehnder干涉仪的性能做了较详细的研究。推导出了该干涉仪的能量传输矩阵 ,分析了两个耦合器的分光比和两臂的臂长差对其输出光谱谱线的影响 ,对于 k=0 .5的反射式 Mach- Zehnder干涉型滤波器比同臂长差的透射式 Mach- Zehnder干涉型滤波器的峰值波长间隔周期小 1倍。
An all-fiber reflected Mach-Zehnder interferometer was studied in details with the interference method for the first time. The energy transmission matrix of the interferometer was deducted. Relationships between the splitting ratios of the couplers, the length difference of two arms and the intensity transmission spectrum were obtained. When k=0.5, the interference pattern fringe period for a reflected Mach-Zehnder interferometer is half of that of a transmitted Mach-Zehnder interferometer. The relationship between the wavelength difference of two adjacent transmission peaks and the difference of two arms was also discussed.
