Tus photodetector yog cov cuab yeej uas hloov lub teeb pom kev rau hluav taws xob. Nyob rau hauv ib lub semiconductor photoodetector, cov yees duab cov yees duab zoo siab los ntawm qhov xwm txheej nkag mus rau sab nraud ntawm cov khoom siv hluav taws xob nyob hauv qab ntawm cov ntaub ntawv ntsuas hluav taws xob thiab ua cov ntawv ntsuas ntsuas hluav taws xob. Txawm hais tias lub luag haujlwm siab tshaj plaws, tus lej Pin tsuas yog tsim ib khub ntawm electron-lub qhov ntawm feem ntau, uas yog lub cuab yeej tsis muaj nce sab hauv. Rau kev teb ntau dua, ib qho avalanche photodiode (APD) tuaj yeem siv.
Lub amplification nyhuv ntawm APD ntawm photocurrent yog raws li ionization kev sib tsoo. Nyob rau hauv qee qhov kev mob, cov tshuab hluav taws xob nrawm thiab cov qhov tuaj yeem sib tsoo nrog cov lattice los tsim cov khub tshiab ntawm electron-qhov sib khub. Cov txheej txheem no yog txoj saw tshuaj tiv thaiv, yog li ntawd cov khub electron Yog li ntawd, APD muaj cov lus qhia tau muaj ntau, uas txhim kho lub teeb liab-rau-suab nrov piv ntawm cov cuab yeej. Apd feem ntau yuav siv nyob rau hauv kev sib txuas lus ntev lossis me me kho cov tshuab sib txuas lus nrog lwm cov kev txwv ntawm cov khoom siv kho qhov muag. Tam sim no, ntau tus kws tshaj lij kho qhov muag tau zoo heev txog kev cia siab ntawm APD.
Rofea ntawm kev tsim kho ntawm photodetector keodiode thiab cov suab nrov scenifier, rau kev tshawb fawb cov kev pabcuam kev lag luam customization, kev txhawb nqa thiab kev pabcuam yooj yim tom qab muag. Cov kab khoom lag luam tam sim no suav nrog: analog teeb liab photoodetector, kev kho kom zoo bhotodetector, kev ua lag luam daus, thiab lwm yam.
