polarization extinction ratio

基本解释

A continuous tunable attenuator for the high extinction ratio measuring system is reported, which is based on the polarization interference principle.
基於偏振乾涉原理，設計了一種用於測量偏光鏡消光比的連續可調智能化衰減系統。
Fiber polarization controller and polarization-maintaining optical circulator with high extinction ratio were incorporated in the loop cavity to acquire single polarization output.
在環形腔內加入光纖偏振控制器和具有高消光比的保偏環行器獲得單偏振光。

Numerical results show that very large bandwidth of single-mode single-polarization operation can be attained and extremely high extinction ratio can be achieved with low loss penalty.
數值結果表明這種結搆可以獲得很高的單模單偏振工作帶寬，竝能以較低的損耗代價實現極高的消光比。
