Ukujonga iimfihlakalo zokukhanya: Izicelo ezitsha zeImodyuli ye-electro-optic I-Linbo3 Imodyuli
I-Linbo3 ModulatorImodyuli yesigaba yiyona nto iphambili enokulawula ukutshintsha kwesigaba sokukhanya, kwaye idlala indima ephambili kunxibelelwano lwale mihla kwaye liqonda. Kutsha nje, uhlobo olutsha lweImodyuli yeSigabaUtsalele ingqalelo kubaphandi kunye neenjineli, ezisebenza kumaza amathathu amaza angama-780nm, i-804nm, kunye ne-bandwidth ye-300mhz, i-10ghz, i-10gz, i-20gz kunye ne-40ghz.
Eyona nto ibalulekileyo yale moto yesigaba yi-Bandwidth ephezulu yemodyuli kunye nelahleko yokufakelwa. Ukuphulukana nelahleko kubhekisa ekwehliseni amandla okuqina okanye amandla omqondiso obonakalayo emva kokudlula kwimodyuli. Ukuphulukana nelahleko yalo msebenzi wesigaba iphantsi kakhulu, okuqinisekisa ukuthembeka komqondiso, ukuze umqondiso unokugcina amandla aphezulu emva kokucinezelwa.
Ukongeza, i-modulilator yenqanaba inomlinganiswa we-voltage ye-wave ephantsi. I-voltage enesiqingatha se-voltage yivolthi ekufuneka ifakwe kwi-MODCIlatotor ukwenzela ukutshintsha isigaba sokukhanya ngama-180 degrees. I-voltage ephantsi ye-phy-wave ithetha ukuba kuphela i-voltage esezantsi kuyafuneka ukufezekisa utshintsho olubalulekileyo kwisigaba sokukhanya, esinciphisa kakhulu ukusetyenziswa kwamandla kwisixhobo.
Ngokwemimandla yokufunda, le modulila yeSigaba esitsha inokusetyenziswa ngokubanzi kwi-fiber ye-fiber yefibre, i-fiber yonxibelelwano lwefibre, ukulibaziseka kwesigaba (Shifter), kunye nonxibelelwano lwenani. Kwi-fiphal fible imvakalelo, imodyuli yesigaba inokuphucula ubuntununtunu kunye nokusonjululwa kwesenzi. Kwi-filical filical fiber, inokuphucula isantya sonxibelelwano kunye nokusebenza kwedatha. Ukulibaziseka kwenqanaba (i-shifter), inokulawula ngokuchanekileyo indlela yokusasazwa kokukhanya; Ngonxibelelwano lwenani, inokusetyenziselwa ukulawula kunye nokufumana amandla omlinganiso.
Ngokubanzi, i-modulator yeSigaba seSigaba esiSiseko isinika iindlela zokulawula ngokufanelekileyo, ezichanekileyo eziya kuzisa utshintsho olufihlakeleyo kumasimi amaninzi. Silindele ukuba le teknoloji iphuhliswe ngakumbi kwaye igqibelele kwixesha elizayo, ityhila iimfihlakalo ezingapheliyo kuthi.
