Xscape Photonics, California-raws li kev pib ua lag luam uas tau tsim kho tshiab laser architecture los txhim kho optical interconnects, hais tias nws nce ntxiv $ 37 lab.
Nqa lub tuam txhab Santa Clara tag nrho cov kev nrhiav nyiaj txiag rau $ 81 lab, cov nyiaj tshiab dhau los ua raws li $ 44 lab tshaj tawm thaum Lub Kaum Hli 2024 thiab los ntawm kev sib koom ua ke ntawm cov peev txheej tshiab ua lag luam Ntxiv, thiab cov backers uas twb muaj lawm suav nrog Nvidia.
Co- tau tsim los ntawm yav dhau los Broadcom tus thawj coj Vivek Raghunathan thiab Columbia University cov xibfwb Michal Lipson thiab Keren Bergman, ntawm lwm tus, Xscape's laser thev naus laus zis yog nyob ib puag ncig kho qhov muag zaus combs, thiab lub tswv yim hais tias zuag-tsav ntom ntom wavelength-livix platforms nyob rau hauv txhua qhov sib txawv zog, bandwidth, thiab redundancy bottlenecks.
Yim -xim laser
Nrog rau kev nce peev, Xscape tau hais tias nws tau tsim yim tshiab - wavelength laser nws hu ua "FalconX". Cov cuab yeej tau piav qhia raws li kev lag luam thawj qhov tsis txaus ntseeg sab nraud laser me me - daim ntawv -factor pluggable (ELSFP) cov cuab yeej muaj peev xwm ntawm emitting tus naj npawb ntawm cov xim, thiab yog tsom rau cov ntawv thov hauv AI cov chaw zov me nyuam.
Txawm li cas los xij, Xscape xav tias lub zuag -tsav mus kom ze - uas nws hu ua "ChromX" - tuaj yeem ntsuas rau ntau lub wavelengths ntxiv, thiab pab pawg tau tsom mus rau emission ntawm 16, 32 thiab, thaum kawg, 128 xim.
"Kev nce bandwidth sai sai, lub zog thiab tus nqi xav tau ntawm AI ua haujlwm tau tsim ib qho tseem ceeb ntawm cov khoom siv kho vajtse, yuam cov neeg tsim khoom siv tsuas yog ib feem ntawm lawv lub peev xwm GPUs, yog li txwv qhov kev hloov pauv ntawm AI nws tus kheej," piav qhia Raghunathan.
"Nrog kev txhawb nqa ntawm peb lub ntiaj teb-cov tub ua lag luam hauv chav kawm, Xscape Photonics tau nrawm rau kev txhim kho nws WDM cov ntaub ntawv daws teeb meem kom khiav tawm cov kev txwv kho vajtse no thiab hauv paus rov xav txog seb cov ntaub ntawv txav mus los ntawm cov ntaub ntawv chaw network.
"FalconX yog qhov kev lag luam thawj zaug Comb laser module nyob rau hauv lub pluggable form factor muaj peev xwm tsim yim wavelengths ntawm lub teeb, powering siab - ceev cov ntaub ntawv txav los tso cai rau tag nrho cov ntaub ntawv chaw ua hauj lwm raws li ib tug loj GPU."
128-xim txoj kev qhia
Ntxiv tus tsim Lee Fixel tau hais tias: "Peb pom qhov no yog lub sijhawm nyuaj rau kev nqis peev hauv kev kho qhov muag laser nyob rau lub sijhawm thaum cov photonics siab dhau los ua qhov tseem ceeb rau AI infrastructure.
"Nrog cov kev tsim kho tshiab xws li FalconX lub yim- wavelength redundant laser thiab ChromX txoj hauv kev rau 128-ntxiv xim, Xscape tab tom hais txog qhov bandwidth bottlenecks uas txwv AI pawg kev ua haujlwm niaj hnub no."
Thaum Xscape tab tom nrhiav rau tus qauv yim -xim FalconX rau ob qho tib si teev - nce thiab ntsuas - tawm kev sib txuas, lub tuam txhab engineers twb tau tsim ua haujlwm 16-xim CombX prototypes hauv kev koom tes nrog chip foundry tus khub Tower Semiconductor.
"Nrog ntau dua 1 W ntawm lub zog kho qhov muag los ntawm ib lub tshuab hluav taws xob pluggable laser, FalconX tsim yim xim uas tuaj yeem muaj zog ntau-terabits-ib -thib ob ntawm cov ntaub ntawv bandwidth," Xscape hais.
"AI pawg tau loj hlob ntau dua kaum-fold hauv ob xyoos dhau los, thiab qhov tsis ua haujlwm ntawm ib lub laser module tuaj yeem cuam tshuam rau lub network, nres qhov ua haujlwm thiab nce tus nqi token.
"Hyperscalers xav tau kaum npaug tsawg dua qhov ua tsis tau zoo piv rau qib laser tam sim no vim qhov kev loj hlob ntawm AI pawg. FalconX muaj kev tsim- nyob rau hauv redundancy thiab ntau txhim khu kev qha Cheebtsam kom tau raws li kev loj hlob pawg neeg xav tau."
