1 MER yog hais txog intrinsic Modulator Extinction Ratio. Qhov extinction ratio uas tau txais feem ntau yog qhov extinction ratio ntawm lub modulator uas tau teev tseg hauv modulator datasheet.
2CiaVπ qhia txog qhov bias voltage ntawm 180◦ thiabVP qhia txog qhov voltage zoo tshaj plaws ntawm Quad points.
3Thov nco ntsoov tias lub zog fais fab ntawm qhov nkag tsis yog hais txog lub zog fais fab ntawm qhov chaw xaiv bias. Nws yog lub zog fais fab siab tshaj plaws uas lub modulator tuaj yeem xa mus rau tus maub los thaum lub zog fais fab ntau ntawm−Vπ rau +Vπ .

1 Polar nyob ntawm lub system RF teeb liab. Thaum tsis muaj RF teeb liab hauv lub system, lub polar yuav tsum yog qhov zoo. Thaum RF teeb liab muaj qhov loj dua li ib qib twg, 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+ point thiab Q-point yuav hloov nrog ib leeg thiab. Polar switch ua rau tus neeg siv hloov pauv
polar ncaj qha yam tsis hloov cov ntsiab lus ua haujlwm.

1 Tsuas yog ib qho kev xaiv yuav tsum tau xaiv ntawm kev siv lub photodiode tswj lossis siv modulator photodiode. Nws raug pom zoo kom siv lub photodiode tswj rau kev sim hauv chav kuaj vim ob qho laj thawj. Ua ntej, lub photodiode tswj tau ua kom zoo. Qhov thib ob, nws yooj yim dua los kho qhov ci ntsa iab ntawm lub teeb nkag. Yog tias siv lub photodiode sab hauv ntawm modulator, thov xyuas kom meej tias qhov tam sim no ntawm photodiode yog sib npaug rau lub zog nkag.
