Imodyuli ye-Electro-opticsisixhobo esiphambili sokulungelelanisa isignali yelaser eqhubekayo kusetyenziswa idatha, amaza erediyo kunye neempawu zewotshi. Izakhiwo ezahlukeneyo zemodyuli zinemisebenzi eyahlukeneyo. Ngokusebenzisa imodyuli ye-optical, kungekuphela nje ukuguquguquka kwamaza okukhanya, kodwa kunye nesigaba kunye nemo ye-polarization yamaza okukhanya anokuguqulwa. Iimodyuli ze-electro-optic zisetyenziswa kakhulu yiMach-Zehnderiimodyuli zokuqinakwayeiimodyuli zesigaba.
IImodyuli yokuqina ye-LiNbO3isetyenziswa ngokubanzi kwinkqubo yonxibelelwano lwe-high-speed optical, i-laser sensing kunye ne-ROF systems ngenxa yokusebenza kakuhle kwe-electro-optic. Uluhlu lwe-R-AM olusekelwe kwisakhiwo se-MZ se-pull-pull kunye ne-X-cut design, ineempawu ezizinzileyo zomzimba kunye neekhemikhali, ezinokuthi zisetyenziswe zombini kwiimvavanyo zebhubhoratri kunye neenkqubo zoshishino.

Iimfuno zomlinganiselo ophezulu wokutshabalala
1. Imodyuli yesistim kufuneka ibe nomlinganiselo ophezulu wokutshabalala. Uphawu lwemodyuli yesixokelelwano lwenza isigqibo sokuba umlinganiselo ophezulu wokutshabalala unokufikelelwa.
2. Ipolarization yesibane sokufaka imodyuli iya kukhathalelwa. Iimodyuli zinovakalelo kwi-polarization. I-polarization efanelekileyo inokuphucula umlinganiselo wokutshabalala ngaphezu kwe-10dB. Kwimifuniselo yelebhu, ngokuqhelekileyo kufuneka isilawuli se-polarization.
3. Abalawuli be-bias abafanelekileyo. Kuvavanyo lwethu lwe-DC extinction ratio, umlinganiselo wokuphela kwe-50.4dB uphunyeziwe. Ngelixa idatabase yemodyuli yenza uluhlu lwe-40dB kuphela. Isizathu solu phuculo kukuba ezinye iimodyuli zihamba ngokukhawuleza kakhulu. I-Rofea R-BC-NAYIPHI na abalawuli be-bias bahlaziya i-voltage ye-bias rhoqo ngomzuzwana we-1 ukuqinisekisa ukuphendula ngokukhawuleza.
I-ROF igxininise kwiisekethe ezidibeneyo ze-electro-optic kunye namacandelo iminyaka elishumi. Senza iimodyuli ezisebenza ngokuphezulu ezidityanisiweyo kunye nokubonelela ngezisombululo kunye neenkonzo ezintsha kubo bobabini abaphandi besayensi kunye neenjineli zeshishini. Iimodyuli zeRofea ezinevoltheji ephantsi yombane kunye nelahleko esezantsi yokufaka yayisetyenziswa ikakhulu kulwabiwo olungundoqo lwe-quantum, iinkqubo zerediyo-over-fiber, iinkqubo zokuva i-laser, kunye nesizukulwana esilandelayo sonxibelelwano lwe-optical telecommunication.
Sikwabonelela ngeemodyuli ezininzi zokwenziwa ngokwezifiso, ezinje nge-1 * 4 uluhlu lweemodyuli zesigaba, i-Vpi ephantsi kakhulu, kunye ne-ultra-high extinction ratio modulators, ezisetyenziswa ikakhulu kwiiyunivesithi nakumaziko. Ukongeza, sikwavelisa iamplifier ye-RF (umqhubi wemodyuli) kunye nesilawuli se-BIAS, umtshina weefoto njl.
Kwixesha elizayo, siya kuqhubeka nokuphucula uluhlu lwemveliso ekhoyo, ukwakha iqela lobugcisa lobuchwephesha, ukuqhubeka nokubonelela abasebenzisi ngomgangatho ophezulu, othembekileyo, iimveliso eziphambili kunye neenkonzo zobugcisa.
