Izinhlelo zokusebenza ezintsha ze-I-Electro-Optic i-modulator yesigaba
I-modulator ye-LiNbO3I-Phase modulator iyisici esibalulekile esingalawula ushintsho lwesigaba segagasi lokukhanya, futhi idlala indima ebalulekile ekuxhumaneni nasekuzweleni kwe-optical yesimanje. Muva nje, uhlobo olusha lwei-modulator yesigabaidonse ukunaka kwabacwaningi nonjiniyela, esebenza ngamaza amathathu obubanzi obungu-780nm, 850nm kanye no-1064nm, kanye nama-bandwidth okuguquguquka afinyelela ku-300MHz, 10GHz, 20GHz kanye no-40GHz.
Isici esibaluleke kakhulu sale modulator yesigaba i-bandwidth ephezulu yokuguquguquka kanye nokulahlekelwa okuphansi kokufakwa. Ukulahlekelwa kokufakwa kubhekisela ekwehleni kokuqina noma amandla esignali yokukhanya ngemva kokudlula ku-modulator. Ukulahlekelwa kokufakwa kwale modulator yesigaba kuphansi kakhulu, okuqinisekisa ubuqotho besignali, ukuze isignali ikwazi ukugcina amandla aphezulu ngemva kokuguquguquka.
Ngaphezu kwalokho, i-phase modulator inesici se-voltage ephansi ye-half-wave. I-voltage ye-half-wave yi-voltage edinga ukusetshenziswa ku-modulator ukuze kushintshwe isigaba sokukhanya ngama-degree angu-180. I-voltage ye-half-wave ephansi isho ukuthi kudingeka i-voltage ephansi kuphela ukuze kufezwe ushintsho olukhulu esigabeni sokubona, okunciphisa kakhulu ukusetshenziswa kwamandla kwedivayisi.
Ngokuphathelene nezinkambu zohlelo lokusebenza, le modulator entsha yesigaba ingasetshenziswa kabanzi ekuzweleni i-optical fiber, ukuxhumana nge-optical fiber, ukubambezeleka kwesigaba (i-shifter), kanye nokuxhumana nge-quantum. Ekuzweleni i-optical fiber, i-phase modulator ingathuthukisa ukuzwela kanye nokuxazululwa kwenzwa. Ekukhulumeni nge-optical fiber, ingathuthukisa isivinini sokuxhumana kanye nokusebenza kahle kokudlulisa idatha. Ekuzweleni kwesigaba (i-shifter), ingalawula ngokunembile isiqondiso sokusabalala kokukhanya; Ekukhulumeni nge-quantum, ingasetshenziswa ukulawula nokulawula izimo ze-quantum.
Sekukonke, i-phase modulator entsha isinikeza izindlela zokulawula ukukhanya ezisebenza kahle futhi ezinembile, ezizoletha izinguquko ezinkulu emikhakheni eminingi. Silindele ukuthi lobu buchwepheshe buthuthukiswe futhi bupheleliswe esikhathini esizayo, buveze izimfihlakalo zokukhanya ezengeziwe kithi.
