Ukadaulo wolumikizirana ndi deta ya Silicon photonic

Silikoni yojambula zithunziukadaulo wolumikizirana ndi deta
M'magulu angapo azipangizo zojambulira zithunzi, zigawo za silicon photonic zimapikisana ndi zipangizo zabwino kwambiri, zomwe zafotokozedwa pansipa. Mwina zomwe timaona kuti ndi ntchito yosintha kwambiri mukulumikizana kwa kuwalandi kupangidwa kwa nsanja zolumikizidwa zomwe zimaphatikiza ma modulators, ma detectors, ma waveguides, ndi zigawo zina pa chip chomwecho zomwe zimalumikizana. Nthawi zina, ma transistors amaphatikizidwanso m'mapulatifomu awa, zomwe zimathandiza kuti amplifier, serialization, ndi feedback zonse ziphatikizidwe pa chip chomwecho. Chifukwa cha mtengo wopangira njira zotere, khama ili limayang'ana kwambiri pakugwiritsa ntchito kulumikizana kwa deta pakati pa peer-to-peer. Ndipo chifukwa cha mtengo wopangira njira yopanga transistor, mgwirizano womwe ukubwera m'mundawu ndi wakuti, kuchokera pakuwona magwiridwe antchito ndi mtengo, ndizomveka kwambiri kuti mtsogolomu muphatikize zida zamagetsi pogwiritsa ntchito ukadaulo wolumikizirana pamlingo wa wafer kapena chip.

Pali phindu lodziwikiratu pakutha kupanga ma chips omwe amatha kuwerengera pogwiritsa ntchito zida zamagetsi ndikuchita kulumikizana kwa kuwala. Ntchito zambiri zoyambirira za silicon photonics zinali mu kulumikizana kwa digito. Izi zimayendetsedwa ndi kusiyana kwakukulu kwa thupi pakati pa ma elekitironi (fermions) ndi ma photon (bosons). Ma elekitironi ndi abwino kwambiri powerengera chifukwa awiriwa sangakhale pamalo amodzi nthawi imodzi. Izi zikutanthauza kuti amalumikizana mwamphamvu. Chifukwa chake, ndizotheka kugwiritsa ntchito ma elekitironi kupanga zida zazikulu zosinthira zosalunjika - ma transistors.

Ma photon ali ndi makhalidwe osiyanasiyana: ma photon ambiri amatha kukhala pamalo amodzi nthawi imodzi, ndipo pazifukwa zapadera kwambiri sasokonezana. Ndicho chifukwa chake n'zotheka kutumiza ma trillions a deta pa sekondi imodzi kudzera mu ulusi umodzi: sizichitika popanga mtsinje wa data wokhala ndi bandwidth imodzi ya terabit.

M'madera ambiri padziko lapansi, ulusi wopita kunyumba ndiye njira yodziwika bwino yopezera deta, ngakhale kuti izi sizinatsimikizidwe kuti ndi zoona ku United States, komwe imapikisana ndi DSL ndi ukadaulo wina. Chifukwa cha kufunikira kosalekeza kwa bandwidth, kufunikira koyendetsa kutumiza deta bwino kwambiri kudzera mu fiber optics kukukulanso pang'onopang'ono. Kukula kwakukulu pamsika wolumikizirana ndi deta ndikuti pamene mtunda ukuchepa, mtengo wa gawo lililonse umachepa kwambiri pomwe voliyumu ikukwera. N'zosadabwitsa kuti khama logulitsa ma silicon photonics layang'ana kwambiri ntchito yayikulu pamapulogalamu apamwamba, afupiafupi, malo owunikira deta ndi makompyuta apamwamba. Mapulogalamu amtsogolo adzaphatikizapo kulumikizana kwa board-to-board, kulumikizana kwa USB-scale short-range, komanso mwina ngakhale kulumikizana kwa CPU core-to-core pamapeto pake, ngakhale zomwe zidzachitike ndi mapulogalamu a core-to-core pa chip zikadali zongopeka. Ngakhale sizinafike pamlingo wamakampani a CMOS, ma silicon photonics ayamba kukhala makampani ofunikira.
