Ukuhlola izimfihlakalo zokukhanya: Izinhlelo zokusebenza ezintsha zeI-Electro-Optic Modulator Amamojula wesigaba se-LiNbO3
I-LiNbO3 moduleI-modulator yesigaba iyisici esibalulekile esingalawula ukuguqulwa kwesigaba samagagasi okukhanya, futhi idlala indima ebalulekile ekuxhumaneni nasekuzweni kwesimanjemanje. Muva nje, uhlobo olusha lwei-modulator yesigabaidonse ukunaka kwabacwaningi nonjiniyela, esebenza ku-wavelengths amathathu we-780nm, 850nm kanye ne-1064nm, ne-modulation bandwidths efika ku-300MHz, 10GHz, 20GHz kanye ne-40GHz.
Isici esibaluleke kakhulu sale modulator yesigaba umkhawulokudonsa wokumodulisa ophezulu kanye nokulahlekelwa okuphansi kokufaka. Ukulahlekelwa kokufaka kubhekisela ekwehleni kokuqina noma amandla esignali yokubona ngemva kokudlula kumodeli. Ukulahlekelwa kokufakwa kwale moduli yesigaba kuphansi kakhulu, okuqinisekisa ubuqotho besignali, ukuze isignali ikwazi ukugcina amandla aphezulu ngemva kokuguqulwa.
Ngaphezu kwalokho, i-modulator yesigaba inesici se-voltage ephansi yesigamu-wave. I-half-wave voltage yi-voltage edinga ukusetshenziswa kumodeli ukuze uguqule isigaba sokukhanya ngamadigri angu-180. I-voltage ephansi ye-half-wave isho ukuthi i-voltage ephansi kuphela edingekayo ukuze kuzuzwe ushintsho olubalulekile esigabeni se-optical, okunciphisa kakhulu ukusetshenziswa kwamandla kwedivayisi.
Ngokuphathelene nezinkambu zohlelo lokusebenza, le modulator yesigaba esisha ingasetshenziswa kabanzi ekuboneni i-fiber optical, ukuxhumana kwe-fiber optical, ukubambezeleka kwesigaba (i-shifter), kanye nokuxhumana kwe-quantum. Ekuzwayo kwe-fiber optical, i-modulator yesigaba ingathuthukisa ukuzwela nokulungiswa kwenzwa. Ekuxhumaneni kwe-fiber optical, ingathuthukisa isivinini sokuxhumana kanye nokusebenza kahle kokudluliswa kwedatha. Ekubambezelekeni kwesigaba (i-shifter), ingakwazi ukulawula ngokunembile ukuqondiswa kokukhanya; Ekuxhumaneni kwe-quantum, ingasetshenziswa ukulawula kanye nokukhohlisa izifunda ze-quantum.
Sekukonke, imoduli yesigaba esisha isinikeza izindlela zokulawula ezisebenza kahle nezinembile, ezizoletha izinguquko ezishintshayo emikhakheni eminingi. Silindele ukuthi lobu buchwepheshe buthuthukiswe futhi bupheleliswe esikhathini esizayo, busembulele izimfihlakalo zokubona okwengeziwe kithi.
