Tshiab Tshuab Ntawm Nyias Silicon Photodetector

Tshuab tshiab ntawmNyias Silicon Photodetector
Photon ntes qauv yog siv los txhim kho lub teeb nqus dej hauv nyiasSilicon Photodetectors
Cov tshuab potonic tau nrawm nrawm hauv ntau cov ntawv thov tawm, nrog rau kev sib txuas lus kho qhov muag, thiab kev kho mob. Txawm li cas los xij, cov dav dav ntawm photonics hauv kev txhim kho kev txhim kho yav tom ntej yog nyob ntawm tus nqi ntawm kev tsim khoomphotodetectors, uas nyob rau hauv lem nyob ntawm ntau ntawm hom ntawm semiconductor siv rau lub hom phiaj ntawd.
Kev lig kev cai, silicon (si) tau tshaj plaws ubiquitous sliciquitous sliciquitous semiconductor hauv kev lag luam hluav taws xob, ntau heev thiaj li muaj kev lag luam ntau nyob ib puag ncig cov khoom no. Hmoov tsis zoo, Si muaj lub teeb tsis muaj zog uas tsis muaj peev xwm nqus tau cov coeffeted nyob ze infrared (NIR) specting piv rau lwm cov soob qub xws li gallium arsenide (gaas). Vim tias qhov no, Gaas thiab lwm cov alloys muaj kev vam meej hauv cov ntawv thov photonic tab sis tsis tau sib xws nrog cov kev tso cai hlau-oxide semiconductor (CMOS) cov txheej txheem siv hauv kev tsim cov hluav taws xob. Qhov no coj mus rau qhov nce ntse nyob hauv lawv cov nqi tsim khoom.
Cov kws tshawb nrhiav tau ua ib txoj hauv kev kom haum rau cov cuab yeej kev ua haujlwm ntawm cov khoom cua, thiab UC Nyob rau hauv lawv cov ntawv tshiab ntawm Advanced photonics nexus, lawv ua rau pom kev ua yeeb yam ntawm lub teeb ci ntsa iab nrog rau Gaas thiab lwm pawg III-v pawg soob Cov. Tus photodetector muaj cov micron-tuab cylindrical silicon phaj muab tso rau ntawm ib tug insulating sastulate, nrog hlau "txuas ntawm tus ntiv tes-diav rawg kev zam los ntawm cov hlau sib ze ntawm sab saum toj ntawm lub phaj. Qhov tseem ceeb, lub lumpy silicon yog sau nrog cov qhov txheej txheej hauv cov qauv ua haujlwm uas ua raws li lub photon chaw ntes. Cov txheej txheem tag nrho ntawm cov cuab yeej ua rau lub teeb ib txwm ua rau khoov los ntawm ze li 90 ° thaum nws tsoo saum npoo, cia nws ua kom tiav rau sab nrauv. Cov qauv kev hais tawm tom qab no nce qhov ntev ntawm lub teeb mus ncig thiab ua kom muaj kev cuam tshuam qeeb, ua rau muaj kev nqus tau ntau dua.
Cov kws tshawb nrhiav tau ua qhov kev ntsuas tsis zoo thiab theoretical tshuaj xyuas kom nkag siab zoo ntawm Photo qauv ntawm Photon, thiab tau ua ntau txoj kev sim sib piv cov photoodetectors nrog thiab tsis muaj lawv. Lawv tau pom tias Photon Capture coj mus rau qhov kev txhim kho loj nyob rau hauv Broadband / nyob sab saud 68% nrog lub ncov ntawm 86%. Nws yog tsim nyog sau cia uas nyob ze rau cov qhab-nees ze, kev nqus cov coeffeted ntawm lub photon detecture ntawm lub photicon ntau dua li cov sillicon, dhau ntawm galium arsenide. Ib qho ntxiv, txawm hais tias tus qauv tsim qauv yog rau 1μm tuab silicon daim phiaj, simulation ntawm 30 nm thiab 100 nm cov yeeb yaj kiab zoo ib yam li kev ua tau zoo sib xws.
Zuag qhia tag nrho, cov txiaj ntsig ntawm txoj kev kawm no ua rau kev txhim kho cov kev ua yeeb yam ntawm cov ntawv thov kev tshaj tawm. Kev nqus tau zoo tuaj yeem ua tiav txawm tias nyob hauv Ultra-nyias cov khaubncaws sab nraud, thiab cov Circuit CoalicS, thiab Circuit Coanitic Capital tuaj yeem khaws cia qis, uas yog qhov tseem ceeb hauv cov tshuab ceev. Ib qho ntxiv, cov lus ntuas tau tshaj tawm cov txheej txheem niaj hnub no thiab yog li muaj peev xwm hloov kho txoj kev Optoelectronics tau muab tso ua ke rau hauv kev ncig ua si. Qhov no, nyob rau hauv lem, yuav pob tau txoj kev rau kev dhia ua kom muaj kev pheej yig urdorast lub computer tes hauj lwm thiab kev yees thev naus laus zis.
