Mach-Zehnder干涉仪 耦合器 波分复用器 Mech-Zehnder interferometer coupler wavelength multiplexers and demultiplexers
摘要
采用光纤3 dB耦合器制成的Mach-Zehnder干涉型波分复用器件可以实现信号波长的合波与分波。Mach-Zehnder干涉仪两臂差ΔL与相位差Δφ直接影响其合分波特性, 复用波长的间隔Δλ与ΔL成反比,通过加长臂长 差可以实现很高的波分密度。但是臂长差越长, 干涉仪对温度越敏感。探讨了一种方法来弥补温度变化所造成的相位差,其波长间隔可做到0.8 nm,稳定性高,消光比好。
Abstract
Fiber-optic Mech-Zehnder interferometer can be used to multiplex and demultiplex wavelengths. The ΔL and Δφ directly influence the properties of M-Z. Through lengthening the ΔL, the density of wavelength dividing can be improved. The longer the ΔL, the more sensitive to temperature the M-Z. The method for making the M-Z work stably is explored. The wavelength separation is 0.8 nm, and the extinction raio is high.
