I-modulator ye-electro-opticiyithuluzi eliyisihluthulelo lokulawula isignali ye-laser eqhubekayo kusetshenziswa idatha, imvamisa yomsakazo kanye nezimpawu zewashi. Izakhiwo ezahlukene ze-modulator zinemisebenzi ehlukene. Nge-modulator ye-optical, akukhona nje kuphela ukuthi amandla wegagasi lokukhanya angashintshwa, kodwa futhi nesimo sesigaba kanye ne-polarization wegagasi lokukhanya singashintshwa. Ama-modulator e-electro-optic asetshenziswa kakhulu yi-Mach-Zehnderama-modulator okuqinafuthiama-modulators esigaba.
II-modulator yokuqina kwe-LiNbO3isetshenziswa kabanzi ohlelweni lokuxhumana lwe-optical olusheshayo, ukuzwa nge-laser kanye nezinhlelo ze-ROF ngenxa yokusebenza kahle kwe-electro-optic. Uchungechunge lwe-R-AM olusekelwe esakhiweni se-MZ push-pull kanye nomklamo we-X-cut, lunezici zomzimba ezizinzile nezamakhemikhali, ezingasetshenziswa kokubili ekuhlolweni kwelabhorethri kanye nezinhlelo zezimboni.

Izidingo zesilinganiso esiphezulu sokuphela
1. I-modulator yesistimu kumele ibe nesilinganiso esiphezulu sokuphela. Isici se-modulator yesistimu sinquma ukuthi isilinganiso esiphezulu sokuphela singafinyelelwa.
2. Ukuhlukaniswa kokukhanya kokufaka kwe-modulator kufanele kunakekelwe. Ama-modulators azwela ukuhlukaniswa. Ukuhlukaniswa okufanele kungathuthukisa isilinganiso sokuphela kwe-extinction ngaphezu kwe-10dB. Ezivivinyweni zelebhu, ngokuvamile kudingeka isilawuli sokuhlukaniswa kwe-polar.
3. Abalawuli be-bias abafanele. Ekuhlolweni kwethu kwesilinganiso sokuphela kwe-DC, isilinganiso sokuphela kwe-50.4dB sifinyelelwe. Ngenkathi ishidi ledatha lomkhiqizi we-modulator libala kuphela i-40dB. Isizathu salokhu kuthuthuka ukuthi amanye ama-modulator ahamba ngokushesha kakhulu. Abalawuli be-bias be-Rofea R-BC-ANY babuyekeza i-voltage ye-bias njalo ngomzuzwana owodwa ukuqinisekisa impendulo esheshayo.
I-ROF ibilokhu igxile kumasekethe ahlanganisiwe e-electro-optic kanye nezingxenye iminyaka eyishumi. Sakha ama-modulator ahlanganisiwe e-optical asebenza kahle kakhulu futhi sinikeza izixazululo nezinsizakalo ezintsha kokubili abacwaningi besayensi kanye nonjiniyela bemboni. Ama-modulator e-Rofea ane-voltage ephansi yokushayela kanye nokulahlekelwa okuphansi kokufakwa asetshenziswa kakhulu ekusabalalisweni kokhiye we-quantum, izinhlelo ze-radio-over-fiber, izinhlelo zokuzwa nge-laser, kanye nokuxhumana kwe-optical kwesizukulwane esilandelayo.
Siphinde sinikeze ama-modulators amaningi akhethekile ukuze kwenziwe ngokwezifiso, njenge-1*4 array phase modulators, i-ultra-low Vpi, kanye ne-ultra-high extinction ratio modulators, ezisetshenziswa kakhulu emanyuvesi nasezikhungweni. Ngaphezu kwalokho, siphinde sikhiqize i-RF amplifier (umshayeli we-modulator) kanye ne-BIAS controller, i-photonics detector njll.
Esikhathini esizayo, sizoqhubeka nokuthuthukisa uchungechunge lwemikhiqizo ekhona, ukwakha ithimba lobuchwepheshe lochwepheshe, siqhubeke nokuhlinzeka abasebenzisi ngemikhiqizo esezingeni eliphezulu, ethembekile, nethuthukisiwe kanye nezinsizakalo zobuchwepheshe.
