Founded hauv 2023, Swiss engineering thiab thev naus laus zis lub tuam txhab Lightium tau mob siab rau muab cov kev pabcuam tsim rau huab hwm coj -tsim- npaj nyias- zaj duab xis lithium niobate photonic chips. Leveraging proprietary manufacturing txheej txheem muaj peev xwm los tuav loj ntau lawm, Lightium muab cov neeg muas zaub ceev ceev muaj peev xwm los ntawm prototyping mus rau loj -scale ntau lawm, ua kom tsim tau tom ntej - tiam photonic chips.
Lightium tau koom nrog- tsim los ntawm Amir Ghadimi, Frédéric Loizeau, thiab Dirk Englund. Amir Ghadimi, CEO, tuav PhD hauv Hluav Taws Xob thiab Hluav Taws Xob Hluav Taws Xob los ntawm ETH Zurich thiab yav dhau los ua tus Kws Tshaj Lij Tshaj Lij ntawm Swiss Center for Electronics thiab Microtechnology (SCEM). Frédéric Loizeau, Tus Thawj Saib Xyuas Nyiaj Tau Los, tuav PhD hauv Microsystems los ntawm ETH Zurich thiab yav dhau los ua tus Thawj Tswj Kev Lag Luam thiab thev naus laus zis ntawm SCEM. Dirk Englund tam sim no yog xibfwb ntawm Hluav Taws Xob Engineering thiab Computer Science ntawm MIT.
Txoj kev loj hlob sai ntawm kev txawj ntse txawj ntse thiab cov khoom zoo li ChatGPT tau ua rau muaj kev loj hlob ntawm cov ntaub ntawv ntim thiab kev siv zog tsis tau pom dua. Thaum xyoo 2030, cov ntaub ntawv chaw ua haujlwm cov ntaub ntawv ntim yuav nce 100-fold, siv 10% ntawm hluav taws xob thoob ntiaj teb. Cov chaw zov me nyuam feem ntau muaj cov pawg loj ntawm cov chaw ua haujlwm hauv nruab nrab (CPUs) thiab cov duab ua haujlwm (GPUs) txhawm rau ua kom cov haujlwm ua haujlwm hnyav thiab xa cov ntaub ntawv ntawm cov txheej txheem no ntawm kev kub ceev ntawm kev sib txuas ntawm qhov muag. Txawm hais tias kev lag luam loj xws li Nvidia tau ua tiav qhov tseem ceeb hauv kev txhim kho GPU kev ua tau zoo, qhov sib txawv tseem ceeb tseem nyob hauv cov ntaub ntawv xa mus ceev thiab lub zog ua haujlwm ntawm optical interconnects. Tam sim no dav siv semiconductor-raws li kev sib txuas thev naus laus zis ntsib teeb meem kev lag luam tseem ceeb ntawm kev nrawm tshaj 800 Gb / s, ncav cuag lub cev txwv ntawm cov khoom siv thiab tsis tuaj yeem ua tau raws li qhov xav tau los tiv thaiv kev loj hlob ntawm cov ntaub ntawv.
Vim yog qhov nyuaj rau kev ua tau raws li qhov xav tau ntawm cov ntaub ntawv silicon, muaj kev lag luam muaj zog thov rau cov khoom siv nrog cov khoom siv hluav taws xob zoo tshaj - kho qhov muag. Cov ntaub ntawv no yuav tsum tsis yog tsuas yog ua tau raws li cov qauv kev ua tau zoo tab sis kuj tiv taus qhov hnyav ib puag ncig ntawm cov chaw khaws ntaub ntawv. Nyias- zaj duab xis lithium niobate yog ib yam khoom uas ua tau raws li cov kev cai saum toj no, tab sis nws kuj yog ib qho ntawm cov ntaub ntawv nyuaj tshaj plaws los ua. Txog rau tam sim no, nws tau txwv rau cov qauv tsim ntawm chav huv huv hauv kev kawm thiab cov tsev kawm tshawb fawb.
