Photodetector Series: Taw Qhia Cov Nqi Photodetector

Taw qhia rauTaug kev Photodetector(Optoelectronic Xaus ntes ntes)
Kev sib npaug photoDetector tuaj yeem muab faib ua cov khoom siv hluav taws xob fiber ntau thiab spatial kho qhov muag txoj kev sib txuas. Sab Hauv, nws muaj ob lub photoDiodes muaj tseeb, lub suab qis, siab bandwidth transtimed Circuitage module amplaced Circuit Court module, thiab cov suab nrov ultra. Nws muaj cov yam ntxwv ntawm cov hom siab tsis kam sib piv, ultra-suab nrov, thiab yog dav siv nyob rau hauv kev sib txuas lus kho qhov muag. Nws tau dhau los ua cov kev tshawb fawb hotspot rau cov lag luam thiab cov tsev kawm qib siab hauv ntau lub tebchaws tsis ntev los no.
Ua haujlwm ntawm cov qauv ntawm kev sib npaug photodetector (Optoelectronic Xaus ntes)
Cov nyiaj tshuav Photodetector siv ob photodiodes nyob rau hauv rov qab bias xeev li lub teeb tau txais chav tsev. Thaum tau txais lub teeb liab teeb liab, cov photocurnes tsim los ntawm ob photodiodes yog rho tawm thiab txuas ntxiv rau qhov teeb liab tam sim no mus rau hauv lub cim hluav taws xob tam sim no. Kev siv tus kheej txo cov qauv yuav ua tau zoo rau cov teeb liab hom los ntawm cov teeb tsa hom kev sib txawv hauv zos thiab tsaus nti txhim kho cov kev tshawb pom muaj peev xwm ntawm cov paib tsis muaj zog.
Cov txiaj ntsig zoo: Siab hom tsis kam sib piv, thiab siab nrhiav bandwidth tuaj yeem ua tau ntau yam xwm txheej.
Qhov tsis zoo: Cov khoom siv hluav taws xob qis, tsuas yog tsim nyog rau lub teeb tsis muaj zog, yuav tsum muaj kev sib xyaw ua ke.

Daim duab: Tus txheej txheem ua haujlwm ua haujlwm ntawm kev sib npaug ntes
Kev ua tau cov khoom seem ntawm kev tshuav nyiaj li cas photodetector (OptoelectronicTshuav Ntes)
1. Teb Chaws
Teb yog hais txog kev ua haujlwm ntawm kev ua tau zoo ntawm kev ua kom pom lub teeb pom kev hauv photocurrent, uas yog qhov sib piv ntawm cov ntawv sau rau lub zog. Xaiv lub photodiode nrog cov kev tshaj tawm tau zoo tuaj yeem txhim kho qhov rhiab ntawm cov nyiaj tshuav ntawm cov ntawv sib npaug.

2. Bandwidth
Lub bandwidth sawv cev rau lub teeb liab zaus ntawm cov zis kos npe ntawm lub photdetector
3. Hom Hom Kev Tsis Txaus Siab
Hom Hom Tsis Txaus Siab yog siv los ntsuas cov qauv ntsuas ntawm cov qauv sib xws los ntawm cov khoom lag luam feem ntau tsis lees txais hom kev xyeej ntawm 25DB.
4. tsi
Cov suab nrov sib npaug: cov teeb liab teeb hluav taws xob lub zog yuav tsum muaj ntawm cov teeb liab-rau-suab nrov piv rau kev ntsuas lub suab nrov ntawm lub cev. Lub ntsiab Cheebtsam ntawm lub suab sib npaug ntes hluav taws xob yog kho qhov muag nrov nrov thiab suab nrov hluav taws xob.

Daim Ntawv Thov Ntawm Kev Sib Npab Photodetector (Optoelectronic Xaus ntes ntes)
Nyob rau hauv xyoo tsis ntev los no, tshuav nyiaj photodetector tau siv dav dav, Fiber txog kev tshawb fawb txog kev ntsuas pa, thiab lwm yam. Kev tshawb fawb txog kev kub ceev, qis suab nrov, siab hom tsis kam sib piv, thiab siab rhiab heev ntawm cov ntes sib npaug tau ua kom muaj kev sib xyaw ua ke thiab muaj kev siv hluav taws xob siab kom tau raws li Cov xwm txheej sib txawv.
