I-silicon photoniciteknoloji yonxibelelwano lwedatha
Kwiindidi ezahlukeneyo zeizixhobo zefotoniki, izinto ze-silicon photonic ziyakhuphisana nezixhobo ezikumgangatho ophezulu, ezixutyushwa ngezantsi. Mhlawumbi oko sikubona njengowona msebenzi uguqula izinto kakhuluunxibelelwano lwe-opticalkukudala amaqonga adibeneyo adibanisa ii-modulators, ii-detectors, ii-waveguides, kunye nezinye izinto kwi-chip efanayo ezinxibelelana. Kwezinye iimeko, ii-transistors nazo zifakiwe kwezi qonga, okuvumela i-amplifier, i-serialization, kunye nempendulo ukuba zonke zidityaniswe kwi-chip enye. Ngenxa yeendleko zokuphuhlisa iinkqubo ezinjalo, lo mzamo ujolise kakhulu kwizicelo zonxibelelwano lwedatha phakathi kontanga. Kwaye ngenxa yeendleko zokuphuhlisa inkqubo yokwenza i-transistor, isivumelwano esivelayo kweli candelo kukuba, ngokwembono yokusebenza kunye neendleko, kunengqiqo enkulu kwikamva elibonakalayo ukudibanisa izixhobo ze-elektroniki ngokwenza itekhnoloji yokubopha kwinqanaba le-wafer okanye le-chip.

Kukho ixabiso elicacileyo ekubeni nokukwazi ukwenza iitships ezinokubala usebenzisa izixhobo ze-elektroniki kwaye zenze unxibelelwano lwe-optical. Uninzi lwezicelo zokuqala ze-silicon photonics zazikunxibelelwano lwedatha yedijithali. Oku kuqhutywa ngumahluko osisiseko wendalo phakathi kwee-electron (fermions) kunye nee-photon (bosons). Ii-electron zilungile kakhulu ekubaleni kuba zombini azinakuba kwindawo enye ngaxeshanye. Oku kuthetha ukuba zisebenzisana ngamandla. Ke ngoko, kunokwenzeka ukusebenzisa ii-electron ukwakha izixhobo ezinkulu zokutshintsha ezingezizo ezantsi - ii-transistors.

Iifotoni zineempawu ezahlukeneyo: iifotoni ezininzi zinokuba kwindawo enye ngaxeshanye, kwaye phantsi kweemeko ezikhethekileyo aziphazamisani. Yiyo loo nto kunokwenzeka ukudlulisa iibhithi zedatha ezili-trillions ngomzuzwana ngefayibha enye: oku akwenziwa ngokudala umsinga wedatha one-bandwidth enye ye-terabit.

Kwiindawo ezininzi zehlabathi, i-fiber ukuya ekhaya yeyona ndlela iphambili yokufikelela, nangona oku kungakhange kungqinwe ukuba kuyinyani eMelika, apho ikhuphisana ne-DSL kunye nezinye iitekhnoloji. Ngenxa yemfuno eqhubekayo ye-bandwidth, isidingo sokuqhuba ukuhanjiswa kwedatha ngokufanelekileyo nge-fiber optics sikhula ngokuqhubekayo. Umkhwa obanzi kwimarike yonxibelelwano lwedatha kukuba njengoko umgama uncipha, ixabiso lecandelo ngalinye liyancipha kakhulu ngelixa umthamo unyuka. Akumangalisi ukuba imizamo yokuthengiswa kwe-silicon photonics igxile kumsebenzi omkhulu kwizicelo eziphezulu, ezimfutshane, ezijolise kumaziko edatha kunye nekhompyutha esebenza kakhulu. Izicelo zexesha elizayo ziya kubandakanya unxibelelwano lwebhodi-ukuya-kwibhodi, unxibelelwano olufutshane lwe-USB-scale, kwaye mhlawumbi nonxibelelwano oluphakathi kwe-CPU ekugqibeleni, nangona okuya kwenzeka ngezicelo ezingundoqo kwi-chip kusacingelwa. Nangona ingekafikeleli kwinqanaba leshishini le-CMOS, i-silicon photonics iqalile ukuba lishishini elibalulekileyo.
