Nyob rau hauv xyoo tas los no, cov kws tshawb nrhiav los ntawm ntau lub teb chaws tau siv ua ke paub lub teeb pom kev zoo ntawm lub teeb infrared thiab siv rau high-rechets, nti lub tshuab hluav taws xob, thiab cov tsheb me me. Tam sim no, nrog kev ntsuas txuas ntxiv ntawm cov kev tshawb fawb no, xws li pom cov khoom siv luv, optogenetic pretes impanted nyob rau hauv lub hlwb, thiab lwm yam.
Qhov loj-teev kev sib xyaw ntawm Optical theem modulators yog qhov tseem ceeb ntawm cov kab muag kho qhov muag rau kev hloov kho kho qhov muag thiab chaw dawb-yoj yoj yoj. Ob lub zog no ry yog qhov tseem ceeb rau kev paub txog ntau yam kev siv. Txawm li cas los xij, rau theem pib ua haujlwm hauv lub teeb pom kev zoo, nws yog qhov tshwj xeeb uas tau raws li cov kev hloov pauv thiab cov kev hloov siab ntawm tib lub sijhawm. Txhawm rau kom tau raws li qhov yuav tsum tau ua, txawm tias qhov feem ntau haum silicon nitride thiab lithium niobate cov ntaub ntawv yuav tsum tau nce cov ntim thiab hluav taws xob noj.
Txhawm rau kom daws tau cov teeb meem no, Michal Lipson thiab Nanfang Yu ntawm Columbia University tsim kom muaj Silicon Nitride Phau Ntawv Qhia Txog Cov Adiabatic micro nplhaib. Lawv tau pov thawj tias lub micro-nplhaib resonator ua haujlwm hauv lub xeev muaj zog. Cov cuab yeej tuaj yeem ua tiav theem kev hloov kho nrog qhov tsawg heev. Piv nrog dog dig waveGuide theem modulators, cov cuab yeej muaj tsawg kawg yog ib qho kev txiav txim ntawm qhov loj txo nyob rau hauv qhov chaw thiab kev siv fais fab. Cov ntsiab lus ntsig txog tau luam tawm hauv xwm photonics.
Michal Lipson, ib tug kws tshaj lij hauv kev ua ke ntawm kev ua ke, hais tias: "Tus yuam sij rau peb ua haujlwm yog siv lub xeev kho qhov muag lub xeev."
The optical resonator is a highly symmetrical structure, which can convert a small refractive index change into a phase change through multiple cycles of light beams. Feem ntau, nws tuaj yeem faib ua peb lub xeev sib txawv: "nyob rau hauv txuas nrog" thiab "nyob rau hauv txuas." Qhov tseem ceeb txuas "thiab" kev sib txuas muaj zog. " Ntawm lawv, "nyob rau hauv txuas txuas" tsuas yog muab cov theem ntxiv uas tsis tseem ceeb, thiab "cuam tshuam loj dua tshiab, yog li cuam tshuam qhov ua tau zoo ntawm lub cuab yeej.
Yuav kom ua tiav tiav 2π theem kev hloov kho thiab qhov kev hloov pauv tsawg, Pawg Kws tshawb xyuas tau tsim lub microring hauv "lub xeev muaj zog". Lub zog txuas ntawm lub zog ntawm lub microring thiab lub "npav" yog tsawg kawg kaum npaug dua li poob ntawm lub microring. Tom qab cov qauv ntawm cov tsim thiab kev ua kom zoo dua, tus qauv qauv kawg tau pom hauv daim duab hauv qab no. Nov yog lub nplhaib resonant nrog tapered dav. Lub nqaim veem Qhov dav dav WaveGuide ib feem ntawm lub teeb ploj ntawm lub microring yog txo los ntawm kev txo cov qhov muag tawm ntawm lub sidau.
Heqing Huang, thawj tus sau ntawm daim ntawv, kuj tau tsim cov khoom me me, thiab lub zog qis pom kev sib xyaw nrog lub vojvoog ntawm tsuas yog 5,8 mw. Lub cim kev sib txawv yog tsawg dua 10%. Dab tsi yog RARER yog tias tus modulator no yog sib npaug rau cov xiav xiav thiab ntsuab nyob hauv lub vis dis aus pom. "
Nanfang yu tseem qhia tawm tias txawm hais tias lawv nyob deb ntawm kev mus txog qib hluav taws xob, lawv cov haujlwm tau nqaim qhov sib txawv ntawm Photonic Swashes thiab tshuab hluav taws xob. "Yog hais tias cov kev siv tshuab dhau los tsuas tso cai rau kev sib koom ua ke ntawm 100 WaveGuide PARDRINT thiab tam sim no peb tuaj yeem ua tiav cov kev ua haujlwm tib yam kom ua tiav ntau yam kev ua haujlwm."
Hauv ntej, cov qauv tsim no tuaj yeem siv rau Electro-Optic Modulators los txo cov chaw nyob thiab hluav taws xob tau noj. Nws kuj tseem siv tau rau lwm qhov kev kho hluav taws xob thiab lwm cov qauv resonator sib txawv. Nyob rau tam sim no, pab pawg tshawb fawb tau koom tes los ua kom pom cov Spectrum Lidar muaj ntau yam kev tsim tawm ntawm theem shifter arrays raws li xws li microrings. Yav tom ntej, nws kuj tseem tuaj yeem siv rau ntau cov ntawv thov xws li txhim kho optical nonlinearity, cov lasers tshiab, thiab cov quartum tshiab.

Beijing Rofoeltronics Co., Ltd. Sib Koom Tes Ua Si " Peb lub tuam txhab feem ntau yog koom nrog kev tshawb fawb ywj pheej thiab tsim qauv, thiab muab cov kev pabcuam tsim kho tshiab, thiab cov kws tshawb fawb txog kev lag luam thiab cov kws tshawb nrhiav kev lag luam. Tom qab xyoo ntawm kev ywj pheej tshiab, nws tau tsim cov khoom nplua nuj thiab zoo nkauj, hluav taws xob siv hauv nroog, hluav taws xob, kev kawm, kev kho mob thiab lwm yam kev lag luam.
