Ubuchwepheshe be-silicon photonics

Njengoba inqubo ye-chip izoncipha kancane kancane, imiphumela ehlukahlukene ebangelwa ukuxhumana iba yinto ebalulekile ethinta ukusebenza kwe-chip. Ukuxhumana kwe-chip kungenye yezithiyo zobuchwepheshe zamanje, futhi ubuchwepheshe be-optoelectronics obusekelwe ku-silicon bungaxazulula le nkinga. Ubuchwepheshe be-silicon photonic buyi-ukuxhumana okubonakalayoubuchwepheshe obusebenzisa i-laser beam esikhundleni sesiginali ye-elekthronikhi ye-semiconductor ukudlulisa idatha. Buwubuchwepheshe besizukulwane esisha obusekelwe ezintweni ze-silicon kanye ne-silicon-based substrate futhi busebenzisa inqubo ekhona ye-CMOS yeidivayisi yokukhanyaukuthuthukiswa nokuhlanganiswa. Inzuzo yayo enkulu ukuthi inesilinganiso sokudlulisa esiphezulu kakhulu, okungenza isivinini sokudlulisa idatha phakathi kwama-cores eprosesa sisheshe izikhathi eziyi-100 noma ngaphezulu, futhi ukusebenza kahle kwamandla nakho kuphakeme kakhulu, ngakho-ke kubhekwa njengesizukulwane esisha sobuchwepheshe be-semiconductor.

Ngokomlando, ama-photonic e-silicon athuthukiswe ku-SOI, kodwa ama-wafer e-SOI ayabiza futhi akuyona into engcono kakhulu kuyo yonke imisebenzi ehlukene ye-photonics. Ngesikhathi esifanayo, njengoba amazinga edatha ekhuphuka, ukuguqulwa kwesivinini esikhulu ezintweni ze-silicon kuba yisithiyo, ngakho-ke izinto ezintsha ezahlukahlukene ezifana namafilimu e-LNO, i-InP, i-BTO, ama-polymer kanye nezinto ze-plasma ziye zathuthukiswa ukuze kufezwe ukusebenza okuphezulu.

Amandla amakhulu e-silicon photonics alele ekuhlanganiseni imisebenzi eminingi kwiphakheji eyodwa nasekukhiqizeni iningi noma yonke, njengengxenye ye-chip eyodwa noma inqwaba yama-chip, kusetshenziswa izikhungo zokukhiqiza ezifanayo ezisetshenziselwa ukwakha amadivayisi e-microelectronic athuthukile (bheka uMfanekiso 3). Ukwenza kanjalo kuzonciphisa kakhulu izindleko zokudlulisa idatha ku-imicu yokukhanyafuthi kudale amathuba ezinhlobo ezahlukene zezicelo ezintsha ezinkulu kuizithombe, okuvumela ukwakhiwa kwezinhlelo eziyinkimbinkimbi kakhulu ngezindleko eziphansi kakhulu.

Kuvela izinhlelo eziningi ze-silicon photonic eziyinkimbinkimbi, ezivame kakhulu ukuxhumana kwedatha. Lokhu kufaka phakathi ukuxhumana kwedijithali okuphezulu kwe-bandwidth kwezinhlelo zokusebenza zebanga elifushane, izinhlelo zokuguqula eziyinkimbinkimbi zezinhlelo zokusebenza zebanga elide, kanye nokuxhumana okuhlangene. Ngaphezu kokuxhumana kwedatha, inani elikhulu lezinhlelo zokusebenza ezintsha zalobu buchwepheshe liyahlolwa kokubili ebhizinisini kanye nase-academia. Lezi zinhlelo zifaka: i-Nanophotonics (nano opto-mechanics) kanye ne-condensed matter physics, i-biosensing, i-nonlinear optics, izinhlelo ze-LiDAR, i-optical gyroscopes, i-RF integratedi-optoelectronics, ama-transceiver omsakazo ahlanganisiwe, ukuxhumana okuhlangene, okushaimithombo yokukhanya, ukunciphisa umsindo nge-laser, izinzwa zegesi, ama-photonics ahlanganisiwe we-wavelength ende kakhulu, ukucutshungulwa kwesignali ngesivinini esikhulu kanye ne-microwave, njll. Izindawo ezithembisayo kakhulu zifaka phakathi i-biosensing, i-imaging, i-lidar, i-inertial sensing, ama-hybrid photonic-radio frequency integrated circuits (RFics), kanye nokucutshungulwa kwesignali.
