Ingcaciso yeMveliso
Okwangoku, kukho iindlela ezintathu zokucinezela i-avalanche ye-InGaAs APDs: ucinezelo lokwenziwa, ucinezelo olusebenzayo kunye nokubonwa kwesango. Ukucinezelwa kwePassive kwandisa ixesha lokufa kweefotodiodes ze-avalanche kwaye kunciphisa ngokunzulu umlinganiselo wokubala ophezulu we-detector, ngelixa ucinezelo olusebenzayo lunzima kakhulu kuba isekethe yocinezelo inzima kakhulu kwaye i-signal cascade ithanda ukukhutshwa. Imowudi yokufumanisa isango ngoku isetyenziswa ekubhaqweni kwefotoni enye. Eyona isetyenziswa kakhulu.
Itekhnoloji yokufumanisa ifotoni enye inokuphucula ngokufanelekileyo ukuchaneka kunye nokusebenza kakuhle kwenkqubo. Kwinkqubo yonxibelelwano ye-laser yendawo, ukuqina kwebala lokukhanya kwesiganeko buthathaka kakhulu, phantse ukufikelela kwinqanaba le-photon. Umqondiso ofunyenwe ngumkhangeli wefoto jikelele uya kuphazamiseka okanye untywiliselwe yingxolo ngeli xesha, ngelixa iteknoloji yokufumanisa ifoton enye isetyenziselwa ukulinganisa olu phawu lokukhanya olubuthathaka kakhulu. Itekhnoloji yokufumanisa ifotoni enye esekwe kwisango le-InGaAs i-avalanche photodiodes ineempawu zokunokwenzeka okuphantsi emva kwe-pulse, i-jitter yexesha elincinci kunye nenani eliphezulu lokubala.
Uluhlu lweLaser ludlale indima ebalulekileyo kwiinkalo ezininzi ezinjengolawulo lwemizi-mveliso, imvakalelo ekude yomkhosi kunye nonxibelelwano lwe-optical space ngenxa yeempawu zayo ezichanekileyo nezikhawulezayo, kunye nenkqubela phambili eqhubekayo yetekhnoloji ye-optoelectronic. Phakathi kwabo, ukongeza kwitekhnoloji yesiqhelo ye-pulse, ezinye izisombululo ezitsha zihlala zicetywayo, njengetekhnoloji yokufumanisa ifoton enye esekwe kwinkqubo yokubala yefotoni, ephucula ukubonwa komqondiso wefotoni enye kwaye icinezele ingxolo ukuphucula. inkqubo. ukuchaneka. Kwi-photon enye, i-jitter yexesha lomtshini we-photon enye kunye nobubanzi be-laser pulse bumisela ukuchaneka kwenkqubo ejikelezayo. Kwiminyaka yakutshanje, iilaser zepicosecond zamandla aphezulu ziye zakhula ngokukhawuleza, ngoko ke ixesha lejitter ye-single-photon detectors iye yaba yingxaki enkulu echaphazela ukuchaneka kwesisombululo senkqubo ye-photon enye.
