Imodeli ye-Electro-opticiyithuluzi eliyinhloko lokushintsha isignali ye-laser eqhubekayo kusetshenziswa idatha, ifrikhwensi yomsakazo namasignali wewashi.Izakhiwo ezahlukene zemoduli zinemisebenzi eyahlukene.Ngokusebenzisa i-optical modulator, amandla okukhanya angashintshwa hhayi kuphela, kodwa futhi isigaba kanye nesimo se-polarization segagasi lokukhanya singashintshwa.Amamojula we-electro-optic asetshenziswa kakhulu yi-Mach-Zehnderama-intensity modulatorsfuthiama-modulators wesigaba.
II-LiNbO3 intensity moduleisetshenziswa kabanzi ohlelweni lwezokuxhumana olunesivinini esiphezulu, i-laser sensing kanye nezinhlelo ze-ROF ngenxa yokusebenza kahle kwe-electro-optic.Uchungechunge lwe-R-AM olusekelwe kusakhiwo se-MZ push-pull kanye ne-X-cut design, inezici ezinzile zomzimba nezamakhemikhali, ezingasetshenziswa kokubili ekuhlolweni kwelabhorethri nezinhlelo zezimboni.

Izidingo zesilinganiso sokuqothulwa okuphezulu
1. Imodeli yesistimu kufanele ibe nesilinganiso esiphezulu sokuqothulwa.Isici semoduli yesistimu sinquma ukuthi isilinganiso esiphezulu sokuqothulwa singafinyelelwa.
2. Ukufakwa kwe-polarization kokukhanya kwemoduli kuzonakekelwa.Ama-modulators ayazwela ku-polarization.I-polarization efanele ingathuthukisa isilinganiso sokuqothulwa ngaphezu kuka-10dB.Ekuhlolweni kwelebhu, ngokuvamile isilawuli se-polarization siyadingeka.
3. Izilawuli zokuchema ezifanele.Esivivinyweni sethu sesilinganiso sokuqothulwa kwe-DC, isilinganiso sokuqothulwa esingu-50.4dB sifinyelelwe.Ngenkathi imininingwane yomshini wokulinganisa yenza uhlu lwama-40dB kuphela.Isizathu salokhu kuthuthukiswa ukuthi amanye ama-modulators akhukhuleka ngokushesha okukhulu.I-Rofea R-BC-NOMA iziphi izilawuli zokuchema zibuyekeza i-voltage echema njalo ngomzuzwana ongu-1 ukuze ziqinisekise ukusabela kwethrekhi esheshayo.
I-ROF ibigxile kumasekethe ahlanganisiwe we-electro-optic kanye nezingxenye iminyaka eyishumi.Senza amamojula adidiyelwe asebenza kahle kakhulu futhi sinikeza izisombululo ezintsha nezinsizakalo zabo bobabili abacwaningi besayensi nonjiniyela bezimboni.Amamoduli e-Rofea ane-voltage ephansi yokushayela kanye nokulahlekelwa kokufaka okuphansi asetshenziswe ngokuyinhloko ekusabalaliseni ukhiye we-quantum, izinhlelo zomsakazo we-radio-over-fiber, amasistimu okuzwa nge-laser, kanye nesizukulwane esilandelayo sokuxhumana ngocingo.
Siphinde futhi sinikeze amamoduli athile athile ukuze enze ngokwezifiso, njengamamodulators wesigaba esingu-1*4 array, i-Vpi ephansi kakhulu, kanye namamodulators wesilinganiso sokuqothulwa okuphezulu kakhulu, asetshenziswa kakhulu emanyuvesi nasezikhungweni.Ukwengeza, siphinde sikhiqize i-RF amplifier (modulator driver) nesilawuli se-BIAS, umtshina wezithombe njll.
Ngokuzayo, sizoqhubeka nokuthuthukisa uchungechunge lomkhiqizo olukhona, ukwakha ithimba lezobuchwepheshe, siqhubeke nokuhlinzeka abasebenzisi ngekhwalithi ephezulu, ethembekile, imikhiqizo ethuthukisiwe kanye nezinsizakalo zobuchwepheshe.
