Lub photodetector yog ib qho khoom siv uas hloov cov teeb liab teeb rau hauv cov teeb liab hluav taws xob. Nyob rau hauv ib tug semiconductor photodetector, tus yees duab-tsim cov cab kuj zoo siab los ntawm qhov teeb meem photon nkag mus rau sab nraud Circuit Court nyob rau hauv qhov siv tsis ncaj voltage thiab tsim ib tug ntsuas photocurrent. Txawm tias nyob rau qhov siab tshaj plaws teb, tus pin photodiode tsuas tuaj yeem tsim ib khub ntawm electron-qhov khub feem ntau, uas yog ib qho khoom siv tsis muaj kev nce hauv. Rau kev teb ntau dua, avalanche photodiode (apd) tuaj yeem siv.
Cov nyhuv amplification ntawm apd ntawm photocurrent yog raws li cov nyhuv ionization kev sib tsoo. Nyob rau hauv tej yam kev mob, lub ceev electrons thiab lub qhov yuav tau txais lub zog txaus los tsoo nrog lub lattice los tsim ib tug tshiab khub ntawm electron-qhov. Cov txheej txheem no yog cov tshuaj tiv thaiv kab mob, yog li cov khub ntawm electron-qhov khub tsim los ntawm lub teeb nqus tau tuaj yeem tsim ntau tus khub electron-qhov thiab tsim cov duab loj thib ob. Yog li ntawd, apd muaj qhov ua haujlwm siab thiab qhov nce hauv sab hauv, uas txhim kho lub teeb liab-rau-nruab nrab ntawm lub cuab yeej. apd yuav tsuas yog siv nyob rau hauv qhov ntev los yog me me optical fiber kev sib txuas lus nrog rau lwm yam kev txwv ntawm lub hwj chim kho qhov muag tau txais. Tam sim no, ntau tus kws tshaj lij kho qhov muag tau pom zoo heev txog qhov kev cia siab ntawm apd.
Rofea nws tus kheej tsim photodetector integrated photodiode thiab tsis tshua muaj suab nrov amplifier Circuit Court, thaum muab ntau yam khoom, rau kev tshawb fawb cov neeg siv muab cov khoom zoo customization kev pab cuam, kev pab cuam thiab yooj yim tom qab-muag kev pab cuam. Cov khoom lag luam tam sim no suav nrog: analog teeb liab photodetector nrog amplification, nce kho photodetector, kev kub ceev photodetector, snow market detector (APD), tshuav nyiaj li cas detector, thiab lwm yam.
