1. MER yog hais txog Modulator Extinction Ratio. Qhov kev ploj tuag piv tau ua tiav yog feem ntau qhov kev ploj tuag ntawm kev hloov pauv tau teev tseg hauv cov ntaub ntawv modulator.
2. Thov nco ntsoov tias input optical fais fab tsis sib haum rau lub hwj chim kho qhov muag ntawm xaiv qhov tsis ncaj ncees lawm. Nws hais txog lub zog kho qhov muag siab tshaj plaws uas tus modulator tuaj yeem xa tawm mus rau tus tswj hwm thaum qhov kev tsis sib haum xeeb ntawm −Vπ rau + Vπ.

1 Polar nyob ntawm qhov system RF teeb liab. Thaum tsis muaj RF teeb liab nyob rau hauv lub system, lub polar yuav tsum zoo. Thaum RF teeb liab muaj amplitude ntau dua ib theem, lub polar yuav hloov ntawm qhov zoo mus rau qhov tsis zoo. Lub sijhawm no, Null point thiab Peak point yuav hloov nrog txhua lwm yam.Q + taw tes thiab Q- taw tes yuav hloov nrog ib leeg.Polar hloov ua rau cov neeg siv hloov lub polar.
ncaj qha yam tsis hloov cov ntsiab lus ua haujlwm.
2Tsuas yog ib qho kev xaiv yuav tsum raug xaiv ntawm kev siv cov tswj photodiode lossis siv modulator photodiode. Nws raug nquahu kom siv tus maub los photodiode rau Lab kev sim rau ob qho laj thawj. Ua ntej, tus maub los photodiode tau ua kom zoo. Thib ob, nws yooj yim dua los kho cov teeb pom kev siv lub teeb pom kev zoo.Yog siv modulator's internal photodiode, thov xyuas kom meej tias cov zis tam sim no ntawm photodiode yog nruj me ntsis proportional rau input zog.
