Itekhnoloji ye-silicon photonics
Njengoko inkqubo yetshiphusi iya kuncipha kancinci kancinci, iziphumo ezahlukeneyo ezibangelwa luqhagamshelo ziba yinto ebalulekileyo echaphazela ukusebenza kwetshiphusi. Uqhagamshelo lwetshiphusi yenye yeengxaki zobugcisa ezikhoyo ngoku, kwaye iteknoloji ye-optoelectronics esekwe kwi-silicon inokusombulula le ngxaki. Itekhnoloji ye-silicon photonic yinkqubounxibelelwano lwe-opticalubuchwepheshe obusebenzisa i-laser beam endaweni yesignali ye-electronic semiconductor ukudlulisa idatha. Bubuchwepheshe besizukulwana esitsha obusekelwe kwi-silicon kunye nezixhobo ze-substrate ezisekelwe kwi-silicon kwaye busebenzisa inkqubo ekhoyo ye-CMOSisixhobo se-opticaluphuhliso kunye nokuhlanganiswa. Inzuzo yayo enkulu kukuba inesantya esiphezulu kakhulu sokudlulisa idatha, nto leyo enokwenza isantya sokudlulisa idatha phakathi kwee-cores zeprosesa sikhawuleze ngokuphindwe kalikhulu nangaphezulu, kwaye ukusebenza kakuhle kwamandla nako kuphezulu kakhulu, ngoko ke ithathwa njengesizukulwana esitsha setekhnoloji ye-semiconductor.
Ngokwembali, ii-silicon photonics ziye zaphuhliswa kwi-SOI, kodwa ii-SOI wafers zibiza kakhulu kwaye azisoloko zizinto ezilungileyo kuzo zonke imisebenzi eyahlukeneyo ye-photonics. Kwangaxeshanye, njengoko amazinga edatha esanda, ukuguqulwa kwesantya esiphezulu kwizixhobo ze-silicon kuya kuba nzima, ngoko ke iintlobo ngeentlobo zezinto ezintsha ezifana neefilimu ze-LNO, i-InP, i-BTO, ii-polymers kunye nezixhobo ze-plasma ziye zaphuhliswa ukuze kufezekiswe ukusebenza okuphezulu.
Amandla amakhulu e-silicon photonics alele ekudibaniseni imisebenzi emininzi kwiphakheji enye kunye nokwenza uninzi lwayo okanye yonke, njengenxalenye yetshiphu enye okanye inqwaba yeetshiphu, kusetyenziswa izixhobo ezifanayo zokuvelisa ezisetyenziselwa ukwakha izixhobo ze-microelectronic eziphambili (jonga uMfanekiso 3). Ukwenza njalo kuya kunciphisa kakhulu iindleko zokudlulisa idatha ngaphezuluiifayibha ezibonakalayokwaye kudalwe amathuba eentlobo ngeentlobo zezicelo ezintsha ezingaqhelekanga kwiiifotoniki, okuvumela ukwakhiwa kweenkqubo ezintsonkothileyo kakhulu ngexabiso eliphantsi kakhulu.
Kukho izicelo ezininzi ezivelayo kwiinkqubo ze-silicon photonic ezintsonkothileyo, ezona zixhaphakileyo kukunxibelelana ngedatha. Oku kuquka unxibelelwano lwedijithali oluphezulu lwe-bandwidth kwizicelo ezimfutshane, izicwangciso ze-modulation ezintsonkothileyo kwizicelo ezikude, kunye nonxibelelwano oluhambelanayo. Ukongeza kunxibelelwano lwedatha, inani elikhulu lezicelo ezintsha zale teknoloji ziyahlolwa kwishishini nakwimfundo ephakamileyo. Ezi zicelo ziquka: iiNanophotonics (nano opto-mechanics) kunye ne-condensed matter physics, i-biosensing, i-nonlinear optics, iinkqubo ze-LiDAR, ii-optical gyroscopes, i-RF integratedi-optoelectronics, ii-transceivers zerediyo ezidibeneyo, unxibelelwano oluhambelanayo, ezintshaimithombo yokukhanya, ukunciphisa ingxolo nge-laser, izinzwa zegesi, ii-photonics ezidityanisiweyo ze-wavelength ende kakhulu, ukucutshungulwa kwesignali ye-high-speed kunye ne-microwave, njl. Iindawo ezithembisayo ngakumbi ziquka ukuva i-biosensing, i-imaging, i-lidar, i-inertial sensing, ii-hybrid photonic-radio frequency integrated circuits (RFics), kunye nokucutshungulwa kwesignali.
