Lithium TANTALATE (LTOI) Kev Kub Ceev Electro-Optic Modulator

Lithium TANTALATE (LTOI) Kev Kub CeevElectro-Optic Modulator

Cov ntaub ntawv thoob ntiaj teb cov ntaub ntawv txuas ntxiv mus, tsav los ntawm cov dav dav ntawm cov thev naus laus zis tshiab xws li 5G thiab ites kev sib tw tseem ceeb rau kev hloov pauv ntawm txhua theem ntawm kev lag luam kho tshiab. Tshwj xeeb, cov tiam tom ntej no yuav tsum muaj kev nce qib ntxiv hauv 200 GBPS hauv ib qho channel thaum txo kev siv hluav taws xob thiab cov nuj nqis. Nyob rau hauv ob peb xyoos dhau los, silicon photonics technology tau tau siv dav nyob rau hauv lub qhov muag transciver transcient kev ua lag luam, feem ntau yog tias silicon photonics tuaj yeem siv cov txheej txheem minned cinos. Txawm li cas los xij, Software Modulators uas cia siab rau cov cab kuj muaj kev phom sij hauv bandwidth, hluav taws xob noj khoom haus, cov cab kuj nqus thiab cov cab kuj mob siab. Lwm cov kev thev naus laus zis nyob rau hauv kev lag luam muaj suav nrog inp, nyias zaj duab xis lithium niobate lynoi, electro-ectrot polymers, thiab lwm yam multi-platform heterogeneous kev daws teeb meem. Lnoi raug suav hais tias yog kev daws teeb meem uas tuaj yeem ua tiav qhov kev ua tau zoo tshaj plaws hauv ultra-kev kub ceev thiab, tam sim no muaj qee cov nyom ntawm cov txheej txheem ntau lawm thiab tus nqi. Tsis ntev los no, pab pawg tau nthuav tawm cov yeeb yaj kiab nyias nyias tantalate (lttoi) kev ua haujlwm zoo nkauj thiab ntau tshaj qhov ua tau zoo ntawm lithium niobate thiab siticon optical platforms hauv ntau daim ntawv thov. Txawm li cas los xij, txog tam sim no, cov cuab yeej tseem ceeb ntawmKev Sib Txuas Lus, Ulla-kev kub ceev Electro-optic modulator, tsis tau pom tseeb hauv LTOI.

Hauv txoj kev tshawb fawb no, cov kws tshawb nrhiav thawj zaug tsim lub Lithic Electro-Optic tantalate ntawm insulator thiab cov tsis muaj microwave ntawm microwave electrode, qhov kev tshaj tawm Ceev txuam ntawm microwave thiab lub teeb yoj hauvElectro-Optical Modulatoryog pom tau. Nyob rau hauv cov nqe lus ntawm kev puas tsuaj ntawm lub microwave electrode, cov kws tshawb fawb hauv cov nyiaj no tau npaj siab dua los txo microwave ploj mus rau 82% piv rau cov dav siv gold electrode.

Daim duab. 1 Ltoi Electro-Optic Modulator qauv qauv, theem sib txuam tsim, microwave electrodode poob test.

Daim duab. 2 qhia qhov kev sim apparatus thiab cov txiaj ntsig ntawm LTOI electro-optic modulator rauKev siv cov rojKev nrhiav kom pom kev ncaj qha (IMDD) hauv kev sib txuas lus kho qhov muag. Cov kev sim qhia tau tias Lroi Electro-OFFIC modulator tuaj yeem xa cov cim ntawm 176 GBD nrog ntsuas cov ntsuas ntawm 25% hauv qab 25% hauv qab ntawm FEC Rau ob qho tib si 200 GBD Pam4 thiab 208 GBD PAM2, BER tau qis dua qhov pib ntawm 15% SD-FEC thiab 7% HD-FEC. Lub qhov muag thiab histic modulator siv tau rau hauv cov tshuab hluav taws xob zoo nkauj nrog cov qhab nia siab siab thiab qis dua yuam kev.

Daim duab. 2 sim ua kev sim ua kom siv Lroi Electro-Optic Modulator rauKev siv cov rojKev nrhiav kom pom kev ncaj qha (IMDD) hauv kev sib txuas lus kho qhov muag (a) sim khoom siv; (b) cov ntsuas ntsuas ntsuas (ber) (c) Muab cov ntaub ntawv siv tau siv tau (huab cua, dashed kab) thiab cuam tshuam nrog cov ntaub ntawv uas muaj txiaj ntsig (ndr (D) Daim duab qhia lub qhov muag thiab cov txheeb cais cov histograms nyob rau hauv Pam2, PAM4 kev hloov kho.

Qhov kev ua haujlwm no ua rau pom thawj lub siab nrawm Electro-optic modulator nrog 3 db bandwidth ntawm 110 GHz. Hauv kev siv kev siv tes ua cov kev sim kom pom tseeb, cov cuab yeej ua tiav ntawm cov ntaub ntawv uas muaj cov khoom siv hluav taws xob uas twb muaj lawm xws li LNOi thiab ntshav modulators. Yav tom ntej, siv ntau dua complexIQ ModulatorCov qauv tsim lossis ntau dua kev ua kom muaj kev ntsuas me me, lossis siv cov khoom siv me me uas yuav tsum tau ua tiav, Lithrz substrates, lithium tantalate yuav tsum tau ua tiav kev sib txuas lus ntawm 2 tus / s lossis siab dua. Ua ke nrog LTOI cov ntsiab lus tshwj xeeb, xws li qis dua birgests, lithium tees, qis-zog thiab ultra-high-high-high-high-inst-tiam siab -Saib cov khoom sib txuas lus kho qhov muag thiab microwave photonics tshuab.
