In 2021, the National Development and Reform Commission and other four departments clearly proposed to lay out the construction of a national hub node of the national integrated computing power network, and accelerate the implementation of the "East and West" project.
Tom qab ntawd, Beijing-Tianjin-Hebei, Yangtze River Delta, Guangdong-Hong Kong-Macao Greater Bay Area thiab lwm qhov chaw tau teb rau qhov kev hu xov tooj thiab txuas ntxiv tsim kev tsim kho. lub teb chaws suav fais fab network hub nodes.
In this regard, a number of industry research reports believe that the large-scale deployment of data centers with "East and West" will definitely detonate the optical communication industry, of which the optical chip and optical module industry will benefit first.
The iteration of optical communication is accelerated, and "old technology" ushered in new development
Kev txhim kho ntawm txoj kev siv tshuab ntawm kev sib txuas lus kho qhov muag yog nyob ntawm kev tsim kho tshiab ntawm kev siv tshuab. Nrog rau kev sib txuas lus kho qhov muag tam sim no thiab cov qauv kev hloov kho tau dhau los ua ntau thiab nyuaj, cov kev sib txuas lus kho qhov muag thiab cov qauv tau hloov mus rau tus nqi ntawm 800bit / s, thiab yuav mus txog qib Tbit / s yav tom ntej. Nws yog qhov yuav tsum tau ceev nrooj los tsim kho qhov muag sib txuas lus chips thiab modules nrog kev sib koom ua ke ntau dua thiab tus nqi qis dua.
At this time, a technology proposed as early as the last century reappeared in people's sight.
Kev txhim kho ntawm silicon-raws li optoelectronic thev naus laus zis tau pib hauv xyoo 1980s. Soref nrhiav pom cov nyhuv plasmonic dispersion nyob rau hauv crystalline silicon, uas muab lub hauv paus theoretical rau silicon -raws li electro- optic modulation.
The core concept of silicon photonics technology is "replacing electricity with light", that is, using laser beams instead of electronic signals for data transmission. Silicon photonics technology integrates optical devices and electronic components in silicon photonics modules into an independent microchip, which deeply integrates optical signal processing and electrical signal processing, and finally realizes "optical interconnection" in the true sense.
Silicon-raws li optoelectronic thev naus laus zis muaj qhov ultra- siab bandwidth, ultra- tus nqi nrawm thiab siab tiv thaiv - cuam tshuam cov yam ntxwv ntawm lub teeb, nrog rau qhov zoo ntawm microelectronics technology hauv loj- nplai kev sib koom ua ke, kev siv hluav taws xob tsawg, tus nqi qis, thiab lwm yam, thiab yog qhov tsim nyog rau siab -kev ceev thiab txoj kev sib txuas lus kho qhov muag yav tom ntej. Nyob rau tib lub sijhawm, nws tuaj yeem ua tau raws li qhov ntev -cov ntaub ntawv kis tau tus mob thiab luv-qhov deb loj- muaj peev xwm xa cov ntaub ntawv ntawm microelectronic chips. Los ntawm kev sib koom ua ke monolithic nrog microelectronic integrated circuits, siab -ceev thiab qis- fais fab ntawm -chip interconnection tuaj yeem paub, ua txhaum cov ntaub ntawv sib cuam tshuam ntawm microelectronic processors. txuas lub raj mis.
Thaum kawg ntawm xyoo tas los, Alibaba DAMO Academy tau tshaj tawm kaum qhov kev siv thev naus laus zis rau xyoo 2022, uas yog: AI rau Kev Tshawb Fawb, co- hloov pauv ntawm cov qauv loj thiab me, silicon photonics chips, ntsuab zog AI, hloov pauv hloov pauv cov neeg hlau, siab -kev kho mob ceev ceev, kev siv thoob ntiaj teb kev ceev ntiag tug, satellite ntawm -kev xam phaj, huab- kev koom ua ke hauv network, thiab XR Internet.
Among them, silicon photonics chips have sprung up, leading a revolution in the field of chips, integrating the advantages of photonics and electronics, breaking through the limitations of Moore's Law, and meeting the explosive computing power demand brought by artificial intelligence and cloud computing. It is expected that in the next three years, silicon photonics chips will carry high-speed information transmission in large data centers.
Optical chips leverage data center tsim los ua qhov chaw kub tshiab
Optical nti yog cov cuab yeej tseem ceeb hauv kev sib txuas lus kho qhov muag. Raws li cov khoom siv kho qhov muag siv silicon photonics thev naus laus zis, silicon photonics nti yog ib hom tshiab ntawm kev sib koom ua ke uas tsim cov khoom siv silicon photonics thiab cov khoom siv los ntawm cov txheej txheem yam ntxwv. Qhov zoo ntawm silicon photonics kev koom ua ke feem ntau suav nrog kev siv hluav taws xob tsawg, kev sib koom ua ke siab, txo ntim, thiab kev sib txuas nrawm dua los ntawm kev xa cov ntaub ntawv los ntawm cov xov xwm photonic. Nyob rau tib lub sijhawm, silicon photonics thev naus laus zis tuaj yeem kuaj hauv cov khoom siv los ntawm txoj hauv kev xws li kev sim wafer, thiab kev ntsuas kev ua haujlwm tau zoo dua qub.
Silicon-raws li optoelectronic thev naus laus zis muaj qhov zoo ntawm kev sib koom ua ke siab. Tab sis tib lub sijhawm, kev sib koom ua ke siab kuj tso siab rau cov kev xav tau siab dua rau cov khoom ntim ntim tshuab. Lub ntim ntawm silicon-raws li optoelectronic chips yuav tsum tau siab precision thiab yog technically nyuaj. Nyob rau theem no, tus nqi ntim ntawm silicon-raws li optoelectronic chips txawm suav txog li 10 feem pua ntawm tag nrho cov nqi ntawm silicon-raws li optoelectronic modules. Txoj kev loj hlob ntawm tsawg- nqi, siab- kev ntseeg tau ntawm silicon-raws li optoelectronic nti ntim tshuab yog ib qho ntawm cov kev cov nyom uas ntsib qhov loj -scale industrialization ntawm silicon{{9} }raws li optoelectronics.
Cov ntaub ntawv chaw yog ib qho kev lag luam tseem ceeb rau kev lag luam kev sib txuas lus kho qhov muag. Nws yog qhov kev txhawb nqa yooj yim rau kev nqa cov tshuab hluav taws xob digital thiab cov ntaub ntawv xov xwm hauv ntau qhov kev lag luam. Nws tseem yog lub luag haujlwm tseem ceeb rau kev txhawb nqa kev txhim kho kev lag luam hauv txhua qhov chaw ntawm lub neej. Piv nrog rau cov khoom siv kho qhov muag zoo tib yam, silicon optical modules muaj qhov zoo ntawm kev siv hluav taws xob tsawg, kev sib koom ua ke thiab kev kub ceev. Rau cov chaw zov me nyuam uas xav tau ntau qhov kho qhov muag modules, qhov zoo tshaj plaws ntawm silicon optical modules yog tus nqi qis.
Yog tias silicon photonics chips tau siv dav hauv thaj chaw ntawm cov chaw zov me nyuam, kho qhov muag suav nrog silicon photonics raws li cov tub ntxhais kawm yuav ua rau muaj kev vam meej ntawm neural tes hauj lwm, yog li cuam tshuam rau kev loj hlob ntawm kev lag luam digital.
