Nco tseg:
1 * hais txog lub hwj chim ntau input rau lub module thaum lub modulator tso zis ntau tshaj. Rau qhov qis taw tes tswj ntawm lub modulator nrog ib tug siab extinction piv, lub input zog yuav tsum tau kom tsim nyog nce; Nrog tshwj xeeb cov kev xav tau ntawm lub zog nkag, koj tuaj yeem kho qhov sib txuas sab hauv thiab ntsuas qhov ntsuas tau nce, thov sab laj muag thaum tso xaj.
2 * Thaum tso qhov kev txiav txim, thov qhia qhov ua haujlwm wavelength, uas yuav tsum tau ua kom zoo raws li kev ua haujlwm wavelength.
3 * switching extinction ratio kuj nyob ntawm qhov hloov pauv hloov pauv theem ntawm tus modulator nws tus kheej.

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 ib leeg.Q + taw tes thiab Q- taw tes yuav hloov nrog ib leeg.Polar hloov ua rau cov neeg siv hloov lub ncov qaumteb qabteb
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.
