Izicelo ezintsha zeI-Electro-Optic imodyuli yesigaba
Imodulator yeLiNbO3I-Phase modulator yinto ebalulekileyo enokulawula utshintsho lwesigaba kwi-light wave, kwaye idlala indima ephambili kunxibelelwano lwanamhlanje lwe-optical kunye nokuva. Kutshanje, uhlobo olutsha lweimodyuli yesigabaitsale ingqalelo yabaphandi kunye neenjineli, esebenza ngamaza amathathu e-780nm, 850nm kunye ne-1064nm, kunye ne-bandwidths yokuguquguquka efikelela kwi-300MHz, 10GHz, 20GHz kunye ne-40GHz.
Eyona nto ibalulekileyo kule modulator yesigaba yi-bandwidth ephezulu yokuguquguquka kunye nokulahleka okuphantsi kokufakelwa. Ukulahleka kokufakelwa kubhekisa ekunciphiseni amandla okanye amandla esignali ye-optical emva kokudlula kwi-modulator. Ukulahleka kokufakelwa kwale modulator yesigaba kuphantsi kakhulu, okuqinisekisa ukuthembeka kwesignali, ukuze isignali ikwazi ukugcina amandla aphezulu emva kokuguqulwa.
Ukongeza, i-phase modulator inophawu lwe-voltage ephantsi ye-half-wave. I-voltage ye-half-wave yi-voltage ekufuneka isetyenziswe kwi-modulator ukuze kutshintshwe i-phase yokukhanya ngama-degrees ali-180. I-voltage ephantsi ye-half-wave ithetha ukuba kufuneka i-voltage ephantsi kuphela ukuze kufezekiswe utshintsho olukhulu kwi-optical phase, nto leyo enciphisa kakhulu ukusetyenziswa kwamandla kwesixhobo.
Ngokuphathelele kwiinkalo zesicelo, le modulator intsha yesigaba ingasetyenziswa kakhulu kwi-optical fiber sensing, optical fiber communication, phase delay (shifter), kunye ne-quantum communication. Kwi-optical fiber sensing, i-phase modulator inokuphucula uvakalelo kunye nesisombululo se-sensor. Kwi-optical fiber communication, inokuphucula isantya sonxibelelwano kunye nokusebenza kakuhle kokudluliselwa kwedatha. Kwi-phase delay (shifter), inokulawula ngokuchanekileyo indlela yokusasazwa kokukhanya; Kwi-quantum communication, inokusetyenziswa ukulawula nokulawula iimeko ze-quantum.
Ngokubanzi, i-phase modulator entsha isinika iindlela zokulawula ukukhanya ezisebenzayo nezichanekileyo, eziza kuzisa utshintsho olukhulu kwiinkalo ezininzi. Silindele ukuba obu buchwepheshe buphuhliswe ngakumbi kwaye bugqitywe kwixesha elizayo, busityhilele iimfihlakalo ezibonakalayo ezingaphezulu.
