Modulator electro-opticwaa aaladda furaha u ah in lagu beddelo calaamadda leysarka joogtada ah iyadoo la adeegsanayo xogta, inta jeer ee raadiyaha iyo calaamadaha saacadaha. Hababka kala duwan ee modulator-ku waxay leeyihiin hawlo kala duwan. Iyada oo loo marayo modulator-ka indhaha, kaliya maaha in la beddelo xoojinta hirarka iftiinka, laakiin sidoo kale marxaladda iyo xaaladda polarization ee hirarka iftiinka ayaa la beddeli karaa. Modulator-ka ugu badan ee la isticmaalo waa Mach-Zehndermodulators xoojintaiyomodulators wajiga.
TheModulator xoojinta LiNbO3waxaa si weyn loogu isticmaalaa nidaamka isgaarsiinta indhaha ee xawaaraha sare leh, dareemayaasha laser iyo nidaamyada ROF sababtoo ah si fiican waxqabadka electro-optic. Taxanaha R-AM ee ku salaysan qaab dhismeedka riix-jiidista MZ iyo naqshadeynta X-cut, waxay leedahay sifooyin jireed iyo kiimiko oo deggan, kuwaas oo lagu dabaqi karo labadaba tijaabooyinka shaybaarka iyo nidaamyada warshadaha.

Shuruudaha saamiga dabar-goynta sare
1. Modulator system waa inuu lahaadaa dabargoyn sare. Sifada modulatorka nidaamka ayaa go'aamisa saamiga ugu badan ee baabi'inta la gaari karo.
2. Polarization of modulator light input waa in la daryeelaa. Modulators waxay u nugul yihiin kala soocida Kala soocida saxda ah waxay wanaajin kartaa saamiga dabar goynta in ka badan 10dB. Tijaabada shaybaadhka, inta badan waxa loo baahan yahay kontaroolaha kala soocida.
3. Xakamaynta eexda saxda ah. Tijaabadeena saamiga baabi'inta DC, saamiga baabi'inta 50.4dB waa la gaadhay. Halka xaashida xogta wax-soo-saarka modulator-ku ay liis garayso kaliya 40dB. Sababta hagaajintan ayaa ah in modulators qaarkood ay si degdeg ah u socdaan. Rofea R-BC-Xiriyaasha eexda kasto waxay cusboonaysiiyaan tamarta eexda 1 ilbiriqsi kasta si loo xaqiijiyo jawaabta degdega ah.
ROF waxa ay diiradda saareysay wareegyada isku dhafan ee korantada-optic iyo qaybaha muddo toban sano ah. Waxaan soo saareynaa wax qabad sare oo isku dhafan oo isku dhafan oo aan siino xalal cusub iyo adeegyo labadaba cilmi-baarayaasha sayniska iyo injineerada warshadaha. Modulators Rofea oo leh koronto yar oo galinta yar iyo luminta galinta hoose ayaa ugu horrayn loo adeegsaday qaybinta furaha quantum-ka, nidaamyada raadiyaha-fiber-ka-dhaafka ah, nidaamyada dareenka laysarka, iyo isgaadhsiinta indhaha ee jiilka xiga.
Waxaan sidoo kale siinaa wax-bedelayaal badan oo gaar ah oo loogu talagalay habeynta, sida 1*4 modulators wejiga array, Vpi aadka u hooseeya, iyo modulators saamiga baabi'inta aadka u sarreeya, oo inta badan lagu isticmaalo jaamacadaha iyo machadyada. Intaa waxaa dheer, waxaan sidoo kale soo saareynaa cod-weyneeye RF (darawalka modulator) iyo kontaroolaha BIAS, qalabka sawir qaadaha iwm.
Mustaqbalka, waxaan sii wadi doonaa horumarinta taxanaha alaabta jira, si loo dhiso koox farsamo xirfadeed, sii wadaan in ay bixiyaan dadka isticmaala tayo sare leh, la isku halayn karo, alaabta horumarsan iyo adeegyada farsamada.
