I-ROF InGaAs Photondetector egijima mahhala i-single-photon detector

Isitholi se-Photondector se-ROF InGaAs esisebenza ngokukhululeka esine-photon eyodwa Isithombe Esifakiwe

Incazelo emfushane:

Lo mkhiqizo uyi-compact near infrared free running single photon detector. Idivayisi eyinhloko isebenzisa i-InGaAs/lnP ngamalungelo obunikazi bokusungula azimele asekhaya. Uma kuqhathaniswa nemikhiqizo efanayo, i-APD inezinkomba zobuchwepheshe ezithuthukisiwe, ukuthembeka kanye nokuhlanganiswa, futhi ingasetshenziswa ekutholeni ukukhanya okuphansi okuhambisanayo njenge-liDAR kanye nokutholwa kokuphila kwe-fluorescence. Izinhlelo zokusebenza zinikeza izixazululo ezingabizi kakhulu.
Lo mkhiqizo usebenzisa i-APD yempendulo engemihle ukuze kufezwe ukucima okusheshayo kwe-avalanche kanye nomsindo ophansi we-elekthronikhi, ukusebenza kahle kokuthola okuphezulu kanye nokubala okumnyama okuphansi ngokwenza ngcono i-elekthronikhi kanye nomklamo wokushisa. Phakathi kwazo, ukusebenza kahle kokuthola okuphezulu kwe-1550nm single photon kungu-> 35%; Ngalesi sikhathi, i-jitter yesikhathi ingaba ngaphansi kuka-80ps; ukusebenza kahle kokuthola. Ku-15%, ukubala okumnyama okuphansi kungu-500 CPS, kanti i-post pulse encane ingu-1% @ isikhathi esifile esingu-5 um; izinga lokubala ukugcwala kufika ku-4MCps @ isikhathi esifile esingu-250ns. Ngaphezu kwalokho, ngezimo ezithile zohlelo lokusebenza, ukusekela ukubandlulula, umkhawulo wokuhlola, isikhathi esifile kanye neminye imingcele yomsebenzi wokucushwa komsebenzisi ukuqinisa ukusebenza kahle kokuthola, izinga lokubala ukugcwala kanye nezinye izinkomba ezithile; Umsebenzi wokusekela ukuguqulwa kwedijithali (TDC) unganqunywa. Ukuze uthole idatha yokubala isikhathi, sekela ukusebenza kwamahhala noma i-trigger yangaphandle. Kunezindlela ezimbili zokusebenza ezitholakalayo.
