Isixhobo sokubona ifoto enye esisebenza ngokukhululekileyo se-ROF InGaAs

Isixhobo sokubona ifoto esinye esisebenza ngokukhululekileyo se-ROF InGaAs Umfanekiso obonisiweyo

Inkcazo emfutshane:

Le mveliso sisitshicileli se-photon esinye esisebenza ngokufihlakeleyo esisebenza nge-infrared. Esi sixhobo siphambili sisebenzisa i-InGaAs/lnP kunye namalungelo obunikazi bobukrelekrele azimeleyo basekhaya. Xa kuthelekiswa neemveliso ezifanayo, i-APD inezalathisi zobugcisa eziphambili, ukuthembeka kunye nokudibanisa, kwaye ingasetyenziselwa ukufumanisa ukukhanya okuphantsi okungalinganiyo okufana ne-liDAR kunye nokufumanisa ubomi bonke be-fluorescence. Izicelo zibonelela ngezisombululo ezingabizi kakhulu.
Le mveliso isebenzisa i-APD yempendulo engalunganga ukufezekisa ukucima ngokukhawuleza kwe-avalanche kunye nengxolo ephantsi ye-elektroniki, ukusebenza kakuhle kokufumanisa kunye nokubala okuphantsi kobumnyama ngokuphucula uyilo lwe-elektroniki kunye nobushushu. Phakathi kwazo, ukusebenza okuphezulu kokufumanisa kwe-1550nm single photon yi> 35%; Ngeli xesha, i-time jitter inokuba phantsi njenge-80ps; ukusebenza kakuhle kwe-Detector. Kwi-15%, inani elincinci lobumnyama yi-500 CPS, kwaye ubuncinci be-post pulse yi-1% @ ixesha lokufa yi-5 um; Izinga lokubala ukugcwala ukuya kuthi ga kwi-4MCps @ ixesha lokufa yi-250ns. Ukongeza, kwiimeko ezithile zesicelo, i-support bias, umda wokuhlola, ixesha lokufa kunye nezinye iiparameter zomsebenzi woqwalaselo lomsebenzisi ukuqinisa ukusebenza kakuhle kokufumanisa, izinga lokubala ukugcwala kunye nezinye izalathisi ezithile; Umsebenzi wokuguqula idijithali yexesha lokuxhasa (TDC) unokumiselwa. Ukufumana idatha yokubala ixesha, inkxaso yokusebenza kwasimahla okanye i-trigger yangaphandle. Kukho iindlela ezimbini zokusebenza.
