1. Mer yog hais txog modulator extinction sib piv. Lub expinction piv tau ua tiav yog feem ntau qhov extinction piv ntawm cov modulator tau teev nyob rau hauv Modulator DatAsheet.
2. Thov sau tseg tias kev tawm tswv yim kho qhov muag tsis sib haum rau lub zog kho qhov muag ntawm kev xaiv bis pois. Nws yog hais txog qhov siab tshaj plaws lub zog uas tus modulator tuaj yeem xa tawm los tswj thaum Bias voltage ranges los ntawm -vπ rau + vπ.

1 Ncej polar nyob ntawm qhov system RF teeb liab. Thaum tsis muaj teeb liab RF hauv cov kab ke, lub ncov qaumteb yuav tsum yog qhov zoo. Thaum RF teeb liab muaj ntau dua li theem, lub ncov qaumteb qabteb yuav hloov pauv ntawm qhov zoo. Nyob rau lub sijhawm no, Null Point thiab Peak point yuav hloov pauv nrog txhua lwm.Q • Taw tes thiab q-point yuav hloov pauv nrog txhua lwm yam li cov neeg siv nyiaj polar
ncaj qha tsis tau hloov cov ntsiab lus ua haujlwm.
2Tsuas yog ib qho kev xaiv yuav raug xaiv ntawm kev siv maub los lub photodiode lossis siv modulator photodiode. Nws raug nquahu kom siv maub los photodiode rau kev sim sim rau ob qho laj thawj. Firstly, tswj cov photodiode muaj ua kom muaj txiaj ntsig zoo. Thib ob, nws yooj yim dua los kho lub tswv yim teeb siv.ci siv cov khoom siv sab hauv sab hauv
Rofea Optoelectronics muaj cov kab khoom lag luam electro-lub teeb ntes, ntsuas hluav taws xob, ntsuas hluav taws xob, dav hlau laser, dav dav laser, Tunle laser, kuaj kho qhov muag, laser dioder tsav, fiber ntau amplififify. Peb tseem muab ntau cov neeg modulators rau kev hloov kho, xws li 1 * 4 Array theem modulators, thiab ultra-siab extinction piv, feem ntau siv nyob rau hauv cov tsev kawm qib siab thiab lub tsev.
Vam tias peb cov khoom yuav pab tau koj thiab koj cov kev tshawb fawb.
