Lithium Niobate (LN) muaj ib qho kev sib txawv, xws li tsis muaj kev cuam tshuam rau cov teebmeem hluav taws xob, thiab cov teebmeem hluav taws xob, thiab cov teebmeem no. Nyob rau tib lub sijhawm, nws muaj qhov zoo ntawm kev dav dav kho kho qhov rai transparency lub qhov rai thiab lub sij hawm ntev. Cov yam ntxwv no ua rau LN ib qho tseem ceeb platform rau lub cim tshiab ntawm kev sib xyaw ua ke. Hauv cov khoom siv kho qhov muag thiab cov yam ntxwv OptoelectRonic, cov yam ntxwv ntawm LN tuaj yeem muab kev txhim kho kev nplua nuj thiab kev siv kho qhov muag, thiab kev pom zoo kho qhov muag. Txawm li cas los xij, vim qhov tsis muaj zog nqus thiab rwb thaiv tsev thaj tsam ntawm lithium niobate, daim ntawv thov sib xyaw ua ke ntawm lithium niobate tseem ntsib teeb meem ntawm kev nyuaj nrhiav tau. Nyob rau hauv xyoo tsis ntev los no, ceeb toom nyob rau hauv no daim teb feem ntau yog suav nrog WaveGuide sib xyaw photoodetectors thiab heterijunction photodetectors.
Cov WaveGuide Inticated Photodetector Raws li Lithium Niobate feem ntau yog tsom rau kev hloov kho qhov muag c-band (1525-1565nm). Nyob rau hauv cov nqe lus ntawm kev ua haujlwm, ln tsuas yog ua lub luag haujlwm ntawm cov kev coj ua, thaum lub caij optoelectronic kev ua haujlwm feem ntau ntawm siliconductors, ii-v pab pawg nqaim bandgiconductors, thiab ob-seem ntaub ntawv. Nyob rau hauv xws li cov architecture, lub teeb tau kis tau los ntawm cov khoom siv lithium niobate ntawm cov khoom siv hluav taws xob raws li kev poob qis, thiab tom qab ntawd ua kom cov paib hluav taws xob thiab hloov nws rau cov hluav taws xob. Qhov zoo yog cov haujlwm siab ua haujlwm siab (~ GHz), cov khoom lag luam qis, loj me me, thiab sib xyaw nrog Photonic Chip koom ua ke. Txawm li cas los xij, vim muaj kev sib cais ntawm cov roj ntsha lithium niobate thiab semiconductor cov ntaub ntawv, tsis tau ua lub luag haujlwm ntawm kev coj ua thiab lwm yam zoo txawv teb chaws tsis tau siv tau zoo. Cov ntaub ntawv semiconduct tsuas yog ua lub luag haujlwm hauv kev hloov pauv lub yees duab thiab tsis muaj kev sib txuas lus nrog txhua lwm yam, ua rau muaj kev ua haujlwm tsawg. Nyob rau hauv cov nqe lus ntawm kev siv tshwj xeeb, txuas ntawm lub teeb los ntawm lub teeb ci los ntawm lub teeb ci mus rau lub lithium niobate kho qhov muag pom thiab cov txheej txheem nruj. Tsis tas li ntawd, lub zog tiag tiag ntawm lub teeb irradiated rau hauv lub semiconductor cheeb tsam channel nyob rau hauv lub cheeb tsam coupling yog qhov nyuaj rau kev ntsuas, uas txwv nws txoj kev ua tau zoo.
Cov ib txwm muajphotodetectorssiv rau kev siv cov ntawv thov cov ntawv thov feem ntau yog ua raws cov ntaub ntawv semiconductor. Yog li ntawd, rau cov lithium niobate, nws cov khoom nqus roj nqus thiab insulating ua rau nws undoubtedly tsis favored los ntawm photodetectorers, thiab txawm tias muaj lub ntsiab lus nyuaj nyob tom teb. Txawm li cas los xij, kev txhim kho ntawm heroobhunction technology nyob rau hauv xyoo tsis ntev los no tau coj kev cia siab rau kev tshawb fawb lithium niobate raws li photodetectors. Lwm cov ntaub ntawv nrog cov kev nqus lub teeb muaj zog lossis zoo heev tuaj yeem ua rau muaj lithium niobate kom them nyiaj rau nws cov shortcomings. Nyob rau tib lub sijhawm, qhov tshwm sim ua rau cov neeg muaj kuab lom ntawm Lithium Niobate vim nws cov qauv hluav taws xob tuaj yeem tswj hwm cov pyroeltricric cov yam ntxwv rau kev tshawb nrhiav OPROELCTRON. Qhov kev ntsuas hluav taws xob thermal no muaj qhov zoo ntawm kev tsav dav thiab tsav tus kheej, thiab tuaj yeem ua tau zoo ua ke thiab haum nrog lwm cov ntaub ntawv. Cov kev cuam tshuam synchronous ntawm thermal thiab cov kev cuam tshuam kev yees duab tau qhib lub sijhawm tshiab rau lithium niobate raws li photodetectors, enable cov khoom siv ntawm qhov zoo ntawm ob qho tib si. Thiab kom ua rau qhov tsis txaus ntseeg thiab ua tiav kev sib koom ua zoo, nws yog lub xov tooj tshawb fawb nyob rau hauv xyoo tas los no. Ib qho ntxiv, kev siv ion immerging, band canineering, thiab kev xaiv tsis zoo los daws cov teeb meem ntawm kev ntes tau lithium niobate. Txawm li cas los xij, vim kev ua haujlwm siab ntawm lithium niobate, daim teb no tseem muaj kev sib koom ua ke zoo xws li kev sib koom ua ke tsawg, thiab tsis muaj txiaj ntsig kev kawm thiab chaw.

Daim duab 1, siv lub zog tsis xws li lub xeev LN Bandgap raws li hluav taws xob cov chaw pabcuam, cov neeg nqa khoom tsis pub them rau hauv lub teeb pom kev zoo. Piv rau yav dhau los pyroelectric ln fileodetectors, uas tau txwv rau cov lus teb ceev ntawm ib puag ncig 100z, qhov noLn PhotodetectorMuaj cov lus teb nrawm nrawm txog 10kHz. Lub caij no, hauv kev ua haujlwm no, nws tau pom tias cov khoom siv magnesium Txoj haujlwm no txhawb kev tshawb fawb txog kev ua haujlwm siab thiabHigh-ceev lnkodetectorsNyob rau hauv kev tsim kho ntawm kev ua haujlwm tag nrho ib-nti ua ke ln photonic chips.
Hauv cov ntsiab lus, cov kev tshawb fawb ntawmNyias Zaj Duab Xis LithHium Niobate photodetectorsMuaj kev tshawb fawb tseem ceeb thiab muaj peev xwm thov kom muaj peev xwm. Nyob rau yav tom ntej, nrog kev txhim kho ntawm thev naus laus zis thiab sib xyaw ua yeeb yaj kiab nyias, nyias zaj duab xis (LN) photodetectors yuav txhim kho rau kev sib koom ua ke ntau dua. Sib txuas ua ke txoj kev sib xyaw ua ke kom ua tiav kev ua tau zoo, cov lus teb yooj yim, thiab cov kev sib xyaw ua ke, thiab muab ntau tus neeg muaj peev xwm rau cov Tshiab tiam ntawm photonics applications.
