摘要
介绍一种能够评价光纤陀螺中各种光学器件 (保偏光纤、耦合器、去偏器和集成光学器件 )的偏振特性的方法。试验装置用于评价保偏光纤的偏振特性 ,系统消光比高达 5 5dB。测试 3m长熊猫型保偏光纤 ,测得最大消光比 2 4 .6dB。
A new method and testing device are introduced which can measure the polarization characteristics of the optical components,such as SLD light source,polarize maintain fiber,coupler,polarizer.This system has good qualities of low cost,simple operating,accurately measuring.Extinction ratio of fiber components can be tested up to 55dB.Tested with that device,panda PM fiber's extinction ratio is 24.6dB
