Ingcaciso yeMveliso
Okwangoku, kukho iindlela ezintathu zokucinezela i-avalanche ye-InGaAs APDs: ucinezelo lokwenziwayo, 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.
