【摘要】 对级联Mach-Zehnder干涉仪进行了理论分析和计算机模拟,并成功制作了50 GHz的平顶二级级联Mach-Zehnder干涉仪型间插复用器,整个结构由3个耦合器和2组干涉臂组成.实际得到的光谱分布与计算机模拟的曲线基本相符,1 dB带宽达到了0.304 nm,占复用波长间隔的76%,得到了比较理想的平顶型的光谱分布,整个器件的附加损耗约为1 dB.更多还原

【Abstract】 By theoretical study and computer simulation on cascaded M-Z interferometer,a flat-top interleaver with a(50 GHz)-spacing,made of three couplers and two interference arms,has been successfully fabricated.Experimental and simulation results are in general agreement.A 1 dB pass-band width of(0.304 nm) that is(76%) of multiplexed wavelength spacing has been realized,and a good flat-top transmission spectrum obtained.The insertion loss is about(1 dB).更多还原
