Lub neej yav tom ntej ntawmelectro optical modulators

Electro optic modulators ua lub luag haujlwm tseem ceeb hauv cov tshuab optoelectronic niaj hnub, ua lub luag haujlwm tseem ceeb hauv ntau qhov chaw los ntawm kev sib txuas lus mus rau quantum xam los ntawm kev tswj cov khoom ntawm lub teeb. Daim ntawv no tham txog cov xwm txheej tam sim no, kev paub dhau los thiab kev txhim kho yav tom ntej ntawm electro optic modulator thev naus laus zis

Daim duab 1: Kev sib piv ntawm qhov sib txawvoptical modulatortechnologies, xws li nyias zaj duab xis lithium niobate (TFLN), III-V hluav taws xob nqus modulators (EAM), silicon-raws li thiab polymer modulators nyob rau hauv cov nqe lus ntawm insertion poob, bandwidth, hwj chim noj, loj, thiab tsim muaj peev xwm.

Cov tsoos silicon-based electro optic modulators thiab lawv cov kev txwv

Silicon-based photoelectric light modulators tau ua lub hauv paus ntawm kev sib txuas lus kho qhov muag tau ntau xyoo. Raws li cov nyhuv plasma dispersion, cov khoom siv no tau ua tiav zoo tshaj plaws hauv 25 xyoo dhau los, nce cov ntaub ntawv hloov pauv los ntawm peb qhov kev txiav txim loj. Niaj hnub nimno silicon-based modulators tuaj yeem ua tiav 4-theem pulse amplitude modulation (PAM4) txog li 224 Gb / s, thiab ntau tshaj 300 Gb / s nrog PAM8 kev hloov kho.

Txawm li cas los xij, silicon-based modulators ntsib cov kev txwv tseem ceeb los ntawm cov khoom siv. Thaum optical transceivers xav tau baud tus nqi ntau dua 200+ Gbaud, bandwidth ntawm cov cuab yeej no nyuaj rau ua tau raws li qhov xav tau. Qhov kev txwv no tshwm sim los ntawm cov khoom muaj txiaj ntsig ntawm silicon - qhov sib npaug ntawm kev zam dhau lub teeb poob thaum tswj kom muaj kev ua tau zoo txaus ua rau muaj kev sib pauv tsis tau.

Emerging modulator technology thiab cov ntaub ntawv

Cov kev txwv ntawm cov tsoos silicon-raws li modulators tau tsav kev tshawb fawb rau lwm cov ntaub ntawv thiab kev koom ua ke technologies. Nyias zaj duab xis lithium niobate tau dhau los ua ib qho kev cog lus zoo tshaj plaws rau lub cim tshiab ntawm kev hloov pauv.Nyias zaj duab xis lithium niobate electro-optic modulatorstau txais cov yam ntxwv zoo heev ntawm cov lithium niobate ntau, suav nrog: lub qhov rais pob tshab, loj electro-optic coefficient (r33 = 31 pm / V) linear cell Kerr effect tuaj yeem ua haujlwm hauv ntau qhov sib txawv wavelength.

Kev nce qib tsis ntev los no hauv cov yeeb yaj kiab nyias nyias lithium niobate thev naus laus zis tau ua tiav cov txiaj ntsig zoo, suav nrog kev hloov pauv kev ua haujlwm ntawm 260 Gbaud nrog cov ntaub ntawv tus nqi ntawm 1.96 Tb / s ib channel. Lub platform muaj qhov tshwj xeeb zoo xws li CMOS-tshaj drive voltage thiab 3-dB bandwidth ntawm 100 GHz.

Kev siv technology tshiab

Txoj kev loj hlob ntawm electro optic modulators yog ze ze rau cov ntawv thov tshwm sim hauv ntau qhov chaw. Hauv thaj tsam ntawm kev txawj ntse txawj ntse thiab cov chaw khaws ntaub ntawv,high-ceev modulatorsNws yog ib qho tseem ceeb rau cov tiam tom ntej ntawm kev sib txuas, thiab AI cov ntawv thov kev siv tau tsav qhov kev thov rau 800G thiab 1.6T pluggable transceivers. Modulator thev naus laus zis kuj tseem siv rau: quantum information processing neuromorphic xam Frequency modulated nruam yoj (FMCW) lidar microwave photon technology

Hauv particular, nyias zaj duab xis lithium niobate electro-optic modulators qhia lub zog nyob rau hauv optical computational processing engines, muab ceev ceev low-power modulation uas accelerates tshuab kev kawm thiab kev txawj ntse kev siv. Xws li cov modulators tuaj yeem ua haujlwm ntawm qhov kub thiab txias thiab haum rau quantum-classical interfaces hauv cov kab superconducting.

Txoj kev loj hlob ntawm tiam tom ntej electro optic modulators ntsib ntau yam teeb meem loj: Cov nqi tsim khoom thiab teev: nyias-zaj duab xis lithium niobate modulators tam sim no txwv rau 150 hli wafer ntau lawm, ua rau cov nqi ntau dua. Kev lag luam yuav tsum nthuav dav wafer loj thaum tuav cov yeeb yaj kiab sib xws thiab zoo. Kev koom ua ke thiab Co-tsim: Kev vam meej ntawm kev txhim khokev ua tau zoo modulatorsyuav tsum muaj kev sib koom tes tsim muaj peev xwm, koom nrog kev sib koom tes ntawm optoelectronics thiab electronic chip designers, EDA lwm tus neeg, founts, thiab ntim cov kws txawj. Manufacturing complexity: Thaum silicon-raws li optoelectronics txheej txheem yog tsawg complex tshaj li advanced CMOS electronics, kev ua tau zoo ruaj khov thiab yield yuav tsum muaj kev txawj ntse tseem ceeb thiab kev tsim cov txheej txheem optimization.

Tsav los ntawm AI boom thiab geopolitical yam tseem ceeb, thaj chaw tau txais kev nqis peev ntau ntxiv los ntawm tsoomfwv, kev lag luam thiab kev lag luam ntiag tug thoob ntiaj teb, tsim cov hauv kev tshiab rau kev sib koom tes ntawm kev kawm thiab kev lag luam thiab cog lus tias yuav ua kom muaj kev tsim kho tshiab.
