Itekhnoloji yonxibelelwano lwedatha yeSilicon photonic

I-silicon yefotoniciteknoloji yonxibelelwano lwedatha
Kwiindidi ezininzi zeizixhobo zefoto, amacandelo e-silicon photonic akhuphisana nezixhobo ezingcono kakhulu zeklasi, ezixutyushwa ngezantsi. Mhlawumbi oko sikuthatha njengowona msebenzi uguqulayo kuwounxibelelwano lwamehlokukuyilwa kwamaqonga adibeneyo adibanisa iimodyuli, ii-detectors, i-waveguides, kunye namanye amacandelo akwi-chip efanayo anxibelelana omnye nomnye. Kwezinye iimeko, ii-transistors nazo zibandakanyiwe kula maqonga, ukuvumela i-amplifier, i-serialization, kunye nempendulo kuzo zonke zidibaniswe kwi-chip efanayo. Ngenxa yeendleko zokuphuhlisa iinkqubo ezinjalo, le nzame ijolise ngokukodwa kwizicelo zonxibelelwano lwedatha yoontanga. Kwaye ngenxa yeendleko zokuphuhlisa inkqubo yokuvelisa i-transistor, imvumelwano evelayo kwintsimi kukuba, ukusuka kwindlela yokusebenza kunye neendleko, yenza ingqiqo kwikamva elibonakalayo ukudibanisa izixhobo zombane ngokwenza iteknoloji yokudibanisa kwi-wafer okanye i-chip. inqanaba.

Kukho ixabiso elicacileyo lokukwazi ukwenza iitshiphusi ezinokuthi zisebenzise izixhobo zombane kunye nokwenza unxibelelwano lwamehlo. Uninzi lwezicelo zokuqala ze-silicon photonics zazikunxibelelwano lwedatha yedijithali. Oku kuqhutywa ngumahluko osisiseko womzimba phakathi kwee-electron (fermions) kunye neephotons (bosons). Ii-electron zilungile kwi-computing kuba zombini azikwazi ukuba kwindawo enye ngexesha elinye. Oku kuthetha ukuba basebenzisane ngamandla omnye nomnye. Ngoko ke, kunokwenzeka ukusebenzisa i-electrons ukwakha izixhobo zokutshintsha ezinkulu ezingabonakaliyo - ii-transistors.

Iifoto zineepropati ezahlukeneyo: ezininzi zeefotoni zinokuba kwindawo enye ngexesha elinye, kwaye phantsi kweemeko ezikhethekileyo aziphazamisi. Yiyo loo nto kunokwenzeka ukuhambisa iitriliyoni zeebhithi zedatha ngesekhondi ngefiber enye: ayenziwa ngokudala umjelo wedatha kunye ne-terabit bandwidth enye.

Kwiindawo ezininzi zehlabathi, ifayibha ukuya ekhaya yeyona paradigm yokufikelela, nangona oku kungangqinwanga ukuba yinyani e-United States, apho ikhuphisana ne-DSL kunye nobunye ubuchwephesha. Ngemfuno eqhubekayo ye-bandwidth, imfuno yokuqhubela phambili ngakumbi nangakumbi ukuhanjiswa kwedatha ngefiber optics nayo ikhula ngokuthe ngcembe. Umkhwa obanzi kwimarike yonxibelelwano lwedatha kukuba njengoko umgama uyancipha, ixabiso lecandelo ngalinye liyancipha kakhulu ngelixa umthamo unyuka. Akumangalisi ukuba iinzame zokuthengisa ze-silicon photonics zigxininise ubuninzi bomsebenzi kwi-volume ephezulu, izicelo ezifutshane, ezijoliswe kumaziko edatha kunye ne-computing ephezulu yokusebenza. Usetyenziso lwexesha elizayo luya kubandakanya ibhodi ukuya ebhodini, i-USB-scale-short-range connectivity, kwaye mhlawumbi ne-CPU yonxibelelwano olungundoqo ekugqibeleni, nangona kuya kwenzeka ntoni nge-core-to-core izicelo kwi-chip isacingelwa ngokufanelekileyo. Nangona ingekafikeleli kwinqanaba leshishini le-CMOS, i-silicon photonics sele iqalisile ukuba lishishini elibalulekileyo.
