ROF InGaAs Photondetector inoongorora photon imwe chete isina kushanda

Mufananidzo wakaratidzwa weROF InGaAs Photondetector isina-photon inomhanya

Tsananguro pfupi:

Chigadzirwa ichi chinoona chiedza che "single photon detector" chinoshanda ne "infrared" chisina infrared. Chishandiso chikuru chinoshandisa InGaAs/lnP nekodzero dzepfuma yepfungwa dzakazvimirira dzemuno. Kana zvichienzaniswa nezvigadzirwa zvakafanana, APD ine zviratidzo zvehunyanzvi zvepamusoro, kuvimbika uye kubatana, uye inogona kushandiswa pakuona chiedza chidiki chisina kuenzana senge liDAR uye fluorescence lifetime detection. Mashandisirwo anopa mhinduro dzinoshanda.
Chigadzirwa ichi chinoshandisa APD ine mhinduro isina kunaka kuti ikwanise kukurumidza kudzimisa mafungu emhepo uye ruzha rwemagetsi rwakaderera, kushanda zvakanaka kwekuona uye kuderera kwerima nekushandisa magadzirirwo emagetsi nekupisa. Pakati pazvo, kushanda zvakanaka kwe1550nm single photon ndeye > 35%; Panguva ino, nguva inogona kunonoka kusvika 80ps; Kushanda zvakanaka kweDetector. Pa15%, kuderera kwerima i500 CPS, uye kuderera kwemoyo mushure mekurova kwemoyo i1% @ nguva yakafa 5 um; Kuwanda kwehuwandu hwekuverenga kusvika 4MCps @ nguva yakafa 250ns. Pamusoro pezvo, kune mamwe mamiriro ekushandisa, kutsigira bias, screening threshold, nguva yakafa uye mamwe ma parameter ebasa rekugadzirisa mushandisi kusimbisa kushanda zvakanaka kwekuona, chiyero chekuverenga kwesimba uye zvimwe zviratidzo zvakananga; Basa rekushandura nguva yedhijitari (TDC) rinogona kutsanangurwa. Kuti uwane data rekuverenga nguva, tsigira kumhanya kwemahara kana gating yekunze yetrigger. Kune nzira mbiri dzekushanda dziripo.
