Tsogolo la ma electro optical modulators

Tsogolo laElectro Optical modulators

Electro optic modulators amatenga gawo lalikulu pamakina amakono a optoelectronic, amatenga gawo lofunikira m'magawo ambiri kuyambira pa kulumikizana kupita ku quantum computing powongolera mawonekedwe a kuwala. Pepalali likukambirana momwe zilili pano, kutsogola kwaposachedwa komanso chitukuko chamtsogolo chaukadaulo wa electro optic modulator

Chithunzi 1: Kuyerekeza kwa magwiridwe antchito osiyanasiyanaOptical modulematekinoloje, kuphatikizapo filimu yopyapyala ya lithiamu niobate (TFLN), III-V magetsi absorption modulators (EAM), silicon-based and polima modulators ponena za kutayika kwa kuyika, bandwidth, kugwiritsa ntchito mphamvu, kukula, ndi kupanga mphamvu.

Traditional silicon-based electro optic modulators ndi zofooka zawo

Ma silicon-based photoelectric light modulators akhala maziko a makina olumikizirana kwazaka zambiri. Kutengera ndi momwe plasma imafalikira, zida zotere zapita patsogolo kwambiri pazaka 25 zapitazi, ndikuwonjezera kusamutsa deta ndi maoda atatu a ukulu. Ma modulators amakono a silicon amatha kukwaniritsa 4-level pulse amplitude modulation (PAM4) mpaka 224 Gb/s, komanso kupitilira 300 Gb/s ndi PAM8 modulation.

Komabe, ma modulator opangidwa ndi silicon amakumana ndi zolepheretsa zomwe zimachokera kuzinthu zakuthupi. Pamene transceivers optical amafuna mitengo ya baud yoposa 200+ Gbaud, bandwidth ya zipangizozi ndizovuta kukwaniritsa zofunikira. Kuchepetsa uku kumachokera kuzinthu zachilengedwe za silicon - kusanja kopewa kutayika kwa kuwala kopitilira muyeso ndikusunga ma conductivity okwanira kumapangitsa kuti pakhale mgwirizano wosapeŵeka.

Ukadaulo waukadaulo wa modulator ndi zida

Zofooka za ma modulators azikhalidwe za silicon zayendetsa kafukufuku muzinthu zina ndi ukadaulo wophatikiza. Filimu yopyapyala ya lithiamu niobate yakhala imodzi mwamapulatifomu odalirika a m'badwo watsopano wa owongolera.Filimu yopyapyala ya lithiamu niobate electro-optic modulatorslandirani makhalidwe abwino kwambiri a lithiamu niobate, kuphatikizapo: zenera lowoneka bwino, lalikulu la electro-optic coefficient (r33 = 31 pm/V) linear cell Kerrs effect imatha kugwira ntchito mumayendedwe angapo

Kupita patsogolo kwaposachedwa kwaukadaulo wocheperako wa filimu ya lithiamu niobate kwabweretsa zotsatira zochititsa chidwi, kuphatikiza modulator yomwe ikugwira ntchito ku 260 Gbaud yokhala ndi ma data a 1.96 Tb / s panjira. Pulatifomu ili ndi maubwino apadera monga CMOS-compatible drive voltage ndi 3-dB bandwidth ya 100 GHz.

Ntchito zamakono zamakono

Kukula kwa ma electro optic modulators kumagwirizana kwambiri ndi ntchito zomwe zikubwera m'magawo ambiri. Pankhani ya intelligence and data centers,ma modulators othamanga kwambirindizofunika kwa m'badwo wotsatira wolumikizana, ndipo ntchito zamakompyuta za AI zikuyendetsa kufunikira kwa 800G ndi 1.6T pluggable transceivers. Ukadaulo wa modulator umagwiritsidwanso ntchito ku: quantum information processing neuromorphic computing Frequency modulated continuous wave (FMCW) lidar microwave photon technology

Makamaka, filimu yopyapyala ya lithiamu niobate ma electro-optic modulators amawonetsa mphamvu mumainjini opangira ma computational processing, omwe amapereka kusinthasintha kwamphamvu kwamphamvu komwe kumafulumizitsa kuphunzira kwamakina ndi kugwiritsa ntchito luntha lochita kupanga. Ma modulators oterowo amathanso kugwira ntchito pazitentha zotsika ndipo ndi oyenera ma quantum-classical interfaces mu mizere ya superconducting.

Kukula kwa ma electro optic modulators a m'badwo wotsatira kumakumana ndi zovuta zingapo zazikulu: Mtengo wopangira ndi kuchuluka kwake: makina opangira mafilimu ochepera a lithiamu niobate pakadali pano amangopanga ma 150 mm wafer, zomwe zimapangitsa kuti pakhale ndalama zambiri. Makampaniwa akuyenera kukulitsa kukula kwa filimuyi kwinaku akusunga filimuyo kuti ikhale yofanana komanso yabwino. Kuphatikiza ndi Co-design: Kukula bwino kwama modulators apamwamba kwambiriimafuna luso lophatikizana, lophatikizana ndi optoelectronics ndi opanga zida zamagetsi zamagetsi, ogulitsa EDA, akasupe, ndi akatswiri onyamula. Kupanga zovuta: Ngakhale njira zopangira ma silicon-based optoelectronics ndizovuta kwambiri kuposa zida zamakono za CMOS, kukwaniritsa magwiridwe antchito ndi zokolola zimafunikira ukadaulo wofunikira komanso kukhathamiritsa kwazinthu zopanga.

Motsogozedwa ndi AI boom ndi geopolitical factor, gawoli likulandila ndalama zochulukirapo kuchokera ku maboma, mafakitale ndi mabungwe wamba padziko lonse lapansi, ndikupanga mwayi watsopano wogwirizana pakati pa ophunzira ndi mafakitale ndikulonjeza kufulumizitsa zatsopano.
