Imodulator ye-electro-opticsisixhobo esibalulekileyo sokulawula isignali yelaser eqhubekayo kusetyenziswa idatha, i-radio frequency kunye neempawu zewotshi. Izakhiwo ezahlukeneyo ze-modulator zinemisebenzi eyahlukeneyo. Nge-optical modulator, ayingotshintsho nje kuphela kumandla e-light wave, kodwa ne-phase kunye ne-polarization state ye-light wave zinokulawulwa. Ii-electro-optic modulators ezisetyenziswa kakhulu yiMach-Zehnderiimodulators zokuqinakwayeiimodulators zesigaba.
IImodulator yokuqina kweLiNbO3Isetyenziswa kakhulu kwinkqubo yonxibelelwano lwe-optical ekhawulezayo, i-laser sensing kunye neenkqubo ze-ROF ngenxa yokusebenza kakuhle kwe-electro-optic. Uthotho lwe-R-AM olusekwe kwisakhiwo se-MZ push-pull kunye noyilo lwe-X-cut, luneempawu zomzimba ezizinzileyo kunye neekhemikhali, ezinokusetyenziswa kuvavanyo lwelabhoratri nakwiinkqubo zoshishino.

Iimfuneko zomlinganiselo ophezulu wokuphela kwezilwanyana
1. I-system modulator kufuneka ibe nomlinganiselo ophezulu wokuphela kwezinto. Uphawu lwe-system modulator lugqiba ekubeni umlinganiselo ophezulu wokuphela kwezinto unokufikelelwa.
2. Ukuphola kwesibane sokufaka i-modulator kufuneka kujongwe. Ii-modulators ziyayiva i-polarization. Ukuphola okufanelekileyo kunokuphucula umlinganiselo wokuphela kwe-extinction ngaphezu kwe-10dB. Kwizilingo zelebhu, ngokuqhelekileyo kufuneka isilawuli se-polarization.
3. Abalawuli be-bias abafanelekileyo. Kuvavanyo lwethu lwe-DC extinction ratio, i-50.4dB extinction ratio ifikelelwe. Ngelixa i-datasheet yomenzi we-modulator idwelisa i-40dB kuphela. Isizathu solu phuculo kukuba ezinye ii-modulators zihamba ngokukhawuleza kakhulu. Abalawuli be-bias be-Rofea R-BC-ANY bahlaziya i-voltage ye-bias rhoqo emva kwemizuzwana e-1 ukuqinisekisa impendulo ekhawulezayo.
I-ROF ibigxile kwiisekethe ezidityanisiweyo ze-electro-optic kunye neenxalenye zayo kangangeminyaka elishumi. Senza ii-modulators ezidityanisiweyo ze-optical ezisebenza kakuhle kwaye sinikezela ngezisombululo ezintsha kunye neenkonzo kubaphandi bezenzululwazi kunye neenjineli zoshishino. Ii-modulators zeRofea ezine-voltage ephantsi yokuqhuba kunye nokulahleka okuphantsi kokufakwa zisetyenziswe kakhulu kwi-quantum key distribution, iinkqubo ze-radio-over-fiber, iinkqubo ze-laser sensing, kunye nonxibelelwano lwe-optical lwesizukulwana esilandelayo.
Sikwabonelela ngee-modulators ezininzi ezithile zokwenza ngokwezifiso, ezinje ngee-modulators ze-1*4 array phase, ii-Vpi ezisezantsi kakhulu, kunye nee-modulators ze-extinction ratio ezikumgangatho ophezulu kakhulu, ezisetyenziswa kakhulu kwiiyunivesithi nakwiindawo zophando. Ukongeza, sikwavelisa i-RF amplifier (umqhubi we-modulator) kunye ne-BIAS controller, i-photonics detector njl.njl.
Kwixesha elizayo, siza kuqhubeka nokuphucula uthotho lweemveliso ezikhoyo, ukwakha iqela lobuchwephesha elinobuchule, siqhubeke nokubonelela abasebenzisi ngemveliso esemgangathweni ophezulu, ethembekileyo, nephucukileyo kunye neenkonzo zobugcisa.
