Ib Lub Phaj Ingaas Photodetector

Ib PhotonIngaas photodetector

Nrog txoj kev loj hlob sai ntawm lub zos, tuspom kom pom lub teeb pomTshuab siv thev naus laus zis thiab xws li siv tshuab lub tsheb khiav mus txog qhov kev siv tshuab hluav taws xob ntxiv, cov kev txiav txim siab tsawg dua ntawm cov kev siv tshuab thev naus laus zis tsis tuaj yeem ntsib qhov kev xav tau tiag tiag. Tib lub photon yog lub zog me me tshaj plaws ntawm lub teeb, thiab lub ntsuas nrog lub peev xwm ntawm ib lub photon nrhiav kom tau yog cov cuab yeej lub teeb tsawg. Piv nrog ingaasAd Photodetector, Ib Leeg-Photo Detectors raws li ingaas APD photoDetector muaj cov lus teb ntau dua, rhiab thiab ua tau zoo. Yog li ntawd, cov kev tshawb fawb ntawm In-Gaas Apd Photodetector Ib Photo Detectors tau raug nqa tawm hauv tsev thiab txawv teb chaws.

Cov kws tshawb fawb los ntawm University of Milan hauv Ltalis ua ntej tsim muaj ob-seem qauv rau simulate tus cwj pwm ntawm ib lub photonAvalanche photodetectorXyoo 1997, thiab muab cov txiaj ntsig los daws cov yam ntxwv hloov ntawm ib lub photon avalanche photodetector. Tom qab ntawd xyoo 2006, cov kws tshawb nrhiav tau siv MocVD los npaj lub ntiaj teb nplooj geometricIngaas apd photodetectorTib lub photon ntes, uas tau nce qhov kev kuaj xyuas ib zaug li 10% los txo cov hluav taws xob muaj kev cuam tshuam thiab txhim kho hluav taws xob hauv cov heterogeneous interface. Nyob rau hauv 2014, los ntawm kev txhim kho zinc doltusion thiab ua kom pom cov qauv ntsug muaj kev txuag nyiaj ntau dua, nce mus txog 30%, thiab ua tiav lub sijhawm jitter txog 87 ps. Xyoo 2016, Sanzaro m li al. kev sib xyaw ua ke ingaas APD photoDetector Ib-photmitected resistor, tsim ib qho kev sib xyaw ua ke ntawm cov qauv monolithic suav tus nqi, yog li txo cov kab mob post-mem tes, thiab Txo lub sijhawm Jitter rau 70 PS. Nyob rau tib lub sijhawm, lwm pab pawg neeg tshawb fawb kuj tau nqa tawm kev tshawb fawb txog ingaas ApdphotodetectorTib lub Photom. Piv txwv li, Princeton Lightwave tau tsim tsim kev tsim ingaas / inpapd ib lub photon ntes nrog phiajcar qauv thiab muab tso rau hauv kev siv khoom lag luam. Lub koom haum Shanghai ntawm kev ua haujlwm ntawm lub cev tau kuaj xyuas cov ntawv pov thawj ntawm VinDse ntawm 3.6 ⁻⁴ 10 ⁻⁴ / NS mem tes ntawm ib mem tes tes ntawm 1.5 MHz. Joseph p li al. Tsim qauv Mesa qauv Ingaas Ad Photodetector, thiab siv ingospbing bandgging, thiab siv cov khoom siv dav kom tau txais ib qho qis tsaus nti suav yam tsis muaj kev cuam tshuam rau kev kuaj pom kev ua tau zoo.

Cov hom kev ua haujlwm ntawm Ingaas Afd photoDetector Kev ntsuas yog qhov chaw ua haujlwm pub dawb tom qab kev ua haujlwm avalanche tshwm sim, thiab rov ua haujlwm tom qab quenching rau ib lub sijhawm. Txhawm rau kom txo qhov cuam tshuam ntawm kev txiav ncua sijhawm, nws yog kwv yees sib faib ua kom tiav Circuit Court, xws li lub siab quenching Circuit Court siv los ntawm R Thew, thiab lwm yam duab (a) , (b) yog qhov yooj yim tswj hwm hluav taws xob tswj hwm thiab cov kev sib txuas nrog Apd photodetector, uas tau tsim los ua haujlwm hauv gated lossis free khiav hom lossis pub dawb Txo cov yav dhau los tsis muaj teeb meem post-mem teeb meem. Ntxiv mus, kev tshawb pom kev ua tau zoo ntawm 1550 nm yog 10%, thiab qhov tshwm sim ntawm cov mem tes yog txo qis dua 1%. Qhov thib ob yog kom paub nrawm quenching thiab rov qab los ntawm kev tswj hwm qib ntawm bias voltage. Txij li nws tsis vam khom rau cov lus taw qhia tswj ntawm avalanche pulse, lub sijhawm ncua ntawm quenching yog txo thiab cov kev paub tab ntawm kev ntsuas tau txhim kho. Piv txwv li, LC Comandar thiab siv hom gated. Ib qho kev sib tw ib leeg-Photo Ntes raws li ingaas / inpapd tau npaj. Qhov kev kuaj pom ib zaug yog ntau dua 55% ntawm 1550 nm, thiab cov post-pulse-pulse probability ntawm 7% tau tiav. Ntawm lub hauv paus no, University of Science thiab Technology ntawm Tuam Tshoj tsim cov kab ke sib txuas ua ke nrog cov hom dawb ingaas apd photodetector ib-photon ntes. Cov cuab yeej sim tau qhia hauv daim duab (c) thiab (d), thiab kev kuaj pom ntawm ntau cov huab nrog ib lub sij hawm daws teeb meem ntawm 1 m.
