【摘要】 利用2×2熔融拉锥型光纤耦合器,提出构建双M-Z干涉系统方案,分析了熔融拉锥耦合器参数特性对双M-Z干涉系统稳定性的影响以及干涉臂输出光强特性。该实验系统低频振动周期为3±0.32 min,系统漂移速率为2.82rad/min。更多还原

【Abstract】 Based on 2×2 optical filber couplers,a simple novel Mach-Zehnder interferometer sysetm was presented.And the effect of Fusion-Elongation couplers parameters on stability of the Mach-Zehnder interferometer system and the output optical intensity of the interferometer were also analyzed.The experiment found that the vibration is slow in a period of 3 ±0.32 min and phase drift is at the rate of 2.82 rad/min.更多还原
