Ukuphonononga iimfihlakalo zokukhanya: izicelo ezintsha zeI-Electro-Optic Modulator Iimodyuli zesigaba se-LiNbO3

Imodyuli yeLiNbO3Imodyuli yeSigaba yinto ephambili enokulawula ukutshintshwa kwesigaba samaza okukhanya, kwaye idlala indima ephambili kunxibelelwano lwanamhlanje kunye nokuziva. Kutshanje, uhlobo olutsha lweimodyuli yesigabaitsale umdla wabaphandi kunye neenjineli, ezisebenza kumaza amathathu e-780nm, 850nm kunye ne-1064nm, kunye ne-modulation bandwidths ukuya kuthi ga kwi-300MHz, 10GHz, 20GHz kunye ne-40GHz.

Eyona nto ibaluleke kakhulu kule modulator yesigaba yi-bandwidth ephezulu yokumodareyitha kunye nelahleko ephantsi yokufaka. Ilahleko yokufaka ibhekisa ekunciphiseni kokuqina okanye amandla ophawu lokukhanya emva kokudlula kwimodyuli. Ukulahleka kokufakwa kwesi sigaba semodyuli siphantsi kakhulu, esiqinisekisa ukunyaniseka komqondiso, ukwenzela ukuba umqondiso unokugcina amandla aphezulu emva kokuguqulwa.

Ukongeza, imodyuli yesigaba inophawu lombane wesiqingatha esisezantsi. I-voltage ye-half-wave yi-voltage efuna ukusetyenziswa kwimodyuli ukuze utshintshe isigaba sokukhanya nge-180 degrees. I-voltage ephantsi yesiqingatha-amaza ithetha ukuba kuphela i-voltage ephantsi efunekayo ukufezekisa utshintsho olubalulekileyo kwisigaba se-optical, esinciphisa kakhulu ukusetyenziswa kwamandla kwesixhobo.

Ngokuphathelele kwimihlaba yesicelo, le modulator yesigaba esitsha ingasetyenziswa ngokubanzi kwi-fiber optical sensing, unxibelelwano lwefiber optical, ukulibaziseka kwesigaba (i-shifter), kunye nonxibelelwano lwe-quantum. Kwi-fiber optical sensing, i-modulator yesigaba inokuphucula uvakalelo kunye nesisombululo senzwa. Kunxibelelwano lwefiber optical, inokuphucula isantya sonxibelelwano kunye nokusebenza kakuhle kokuhanjiswa kwedatha. Kwinqanaba lokulibaziseka (i-shifter), inokulawula ngokuchanekileyo isalathiso sokusasazwa kokukhanya; Kunxibelelwano lwe-quantum, lunokusetyenziswa ukulawula kunye nokulawula iimeko ze-quantum.

Ngokubanzi, imodyuli yesigaba esitsha isinika iindlela ezisebenza kakuhle nezichanekileyo zolawulo lwamehlo, eziya kuzisa utshintsho oluguquguqukayo kwiinkalo ezininzi. Silindele ukuba le teknoloji iphuhliswe ngakumbi kwaye igqibelele kwixesha elizayo, ityhila iimfihlelo ezingaphezulu zamehlo kuthi.
