Ke hobane'ng ha re hloka moralo o mocha?
Marang-rang a Optical neural a potlakile ho feta litharollo tsa setso tse sebelisang likarolo tsa elektroniki. Leseli ho itšehla thajana ha litsela tsa lipontšo, le melapo ea laser e khona ho fetana ntle le tšusumetso e tšoanang. Ka tsela ena, litsela tsohle tsa lipontšo li ka sebetsa ka nako e le 'ngoe, ho lumella litekanyetso tse phahameng tsa ho fetisa data.
Empa ho na le bothata - ha neural network e kholoanyane, e sebelisa matla a mangata. Ho rarolla bothata bona, ho ntse ho ntlafatsoa li-accelerator chips (AI accelerators) tse ntlafatsang phetiso ea data. Leha ho le joalo, ha li lekane hantle kamoo re ka ratang kateng.
Bothata ba ho sebetsa hantle ha matla le ho eketseha ha li-chips tsa optical bo ile ba rarolloa ho MIT le moaho o mocha oa accelerator o fokotsang tšebeliso ea matla a sesebelisoa ka makhetlo a sekete mme o sebetsa le li-neurone tse limilione tse mashome. Bahlahisi ba re nakong e tlang thekenoloji e tla fumana ts'ebeliso litsing tsa data tse sebelisanang le litsamaiso tse rarahaneng tse bohlale le li-algorithms tsa ho ithuta mochini, hape le ho sekaseka lintlha tse kholo.

Chip e ncha e hahiloe motheong oa potoloho ea optoelectronic. Lintlha tse fetisoang li ntse li kentsoe ka mats'oao a mahlo, empa tlhahlobo e leka-lekaneng ea homodyne e sebelisoa bakeng sa ho atisa matrix (). Ena ke mokhoa o lumellang hore u hlahise letšoao la motlakase ho latela tse peli tsa optical.
Tsela e le 'ngoe ea pontšo e sebelisetsoa ho fetisa likhahla tse khanyang ka boitsebiso bo mabapi le li-neuron tse kenang le tse tsoang.

Mohaho o mocha oa accelerator oa AI o hloka ho kenya letsoho le mocha o le mong bakeng sa neuron ka 'ngoe. Ka lebaka leo, palo ea li-photodetectors e lekanngoa le palo ea li-neuron, ho e-na le li-coefficients tsa tsona tse boima.
Mokhoa ona o u lumella ho boloka sebaka ho chip, ho eketsa palo ea litsela tse sebetsang tsa matšoao le ho ntlafatsa tšebeliso ea matla. Hona joale lienjineri tse tsoang MIT li ntse li etsa mohlala o tla leka bokhoni ba moaho o mocha ka ts'ebetso.
Ke mang hape ea ntseng a hlahisa li-photonic chips?
Lintlafatso tsa theknoloji e tšoanang Lightelligence ke qalo e nyane e thehiloeng Boston. Basebetsi ba k'hamphani ba re accelerator ea bona ea AI e tla lumella ho rarolla mathata a ho ithuta ka mochini ka makhetlo a makholo ho feta lisebelisoa tsa khale. Selemong se fetileng, sehlopha se ne se phethela ho etsa mohlala oa sesebelisoa sa bona le ho itokisetsa ho etsa liteko.
E sebetsa tšimong ea li-photonic chips le Cisco. Qalong ea selemo khampani e phatlalalitse qala Luxtera, e qapang li-chips tsa photonic bakeng sa litsi tsa data. Haholo-holo, k'hamphani e hlahisa li-interfaces tsa hardware tse u lumellang hore u kopanye fiber optics ka ho toba ho li-server. Mokhoa ona o eketsa bokhoni ba marang-rang mme o potlakisa phetiso ea data. Lisebelisoa tsa Luxtera li sebelisa li-laser tse khethehileng ho kenyelletsa tlhahisoleseling le li-photodetectors tsa germanium ho li hlakola.

Lik'hamphani tse ling tse kholo tsa IT, joalo ka Intel, le tsona li kentse letsoho ho theknoloji ea optical. Khale ka 2016, ba ile ba qala ho iketsetsa li-chips tsa bona tse ntlafatsang phetiso ea data lipakeng tsa litsi tsa data. Haufinyane tjena, baemeli ba mokhatlo hore ba rera ho kenya ts'ebetsong mahlale ana ka ntle ho litsi tsa data - ka li-lidar bakeng sa likoloi tse itsamaisang.

Ho fihlela joale, theknoloji ea photonic e ke ke ea bitsoa tharollo ea bokahohle. Ts'ebetsong ea bona e hloka litšenyehelo tse kholo bakeng sa lisebelisoa tse ncha tsa tekheniki tsa litsi tsa data. Empa lintlafatso tse joalo ka tse ntseng li ntlafatsoa ho MIT le mekhatlong e meng li tla etsa hore li-optical chips li theko e tlase mme mohlomong li tla li lumella ho phahamisetsoa 'marakeng o moholo oa lisebelisoa tsa setsi sa data.
