Ubuchwepheshe be-silicon photonics

Njengoba inqubo ye-chip izoncipha kancane kancane, imiphumela ehlukahlukene ebangelwa ukuxhumana iba yinto ebalulekile ethinta ukusebenza kwe-chip. I-chip interconnection ingenye yezinkinga zamanje zobuchwepheshe, futhi ubuchwepheshe be-silicon based optoelectronics bungaxazulula le nkinga. Ubuchwepheshe be-silicon photonic buyi-ukuxhumana opticalubuchwepheshe obusebenzisa i-laser beam esikhundleni sesignali ye-electronic semiconductor ukudlulisa idatha. Kuwubuchwepheshe besizukulwane esisha obususelwe ku-silicon kanye nezinto ezisekelwe ku-silicon-based substrate futhi isebenzisa inqubo ekhona ye-CMOSidivayisi yokubonaukuthuthukiswa kanye nokuhlanganiswa. Inzuzo yayo enkulu ukuthi inezinga eliphezulu kakhulu lokudlulisa, elingenza isivinini sokudlulisa idatha phakathi kwama-processor cores izikhathi ezingu-100 noma ngaphezulu ngokushesha, futhi ukusebenza kahle kwamandla nakho kuphezulu kakhulu, ngakho-ke kubhekwa njengesizukulwane esisha se-semiconductor. ubuchwepheshe.

Ngokomlando, ama-silicon photonics athuthukisiwe ku-SOI, kodwa ama-wafers e-SOI ayabiza futhi awawona ngempela impahla engcono kakhulu kuyo yonke imisebenzi ehlukene yezithombe. Ngesikhathi esifanayo, njengoba amanani edatha enyuka, ukuguqulwa kwejubane eliphezulu ezintweni ze-silicon kuba ibhodlela, ngakho-ke izinhlobonhlobo zezinto ezintsha ezifana namafilimu e-LNO, i-InP, i-BTO, ama-polymers nezinto ze-plasma ziye zathuthukiswa ukuze kuzuzwe ukusebenza okuphezulu.

Amandla amakhulu we-silicon photonics asekuhlanganiseni imisebenzi eminingi ephaketheni elilodwa kanye nokukhiqiza okuningi noma yonke, njengengxenye ye-chip eyodwa noma isitaki sama-chips, kusetshenziswa izindawo zokukhiqiza ezifanayo ezisetshenziselwa ukwakha amadivaysi e-microelectronic athuthukile (bona Umfanekiso 3) . Ukwenza kanjalo kuzonciphisa kakhulu izindleko zokudlulisa idathaimicu ye-opticalfuthi udale amathuba ezinhlobonhlobo zezinhlelo zokusebenza ezintsha eziqinileizithombe, okuvumela ukwakhiwa kwezinhlelo eziyinkimbinkimbi kakhulu ngezindleko eziphansi kakhulu.

Izinhlelo zokusebenza eziningi ziyavela zezinhlelo eziyinkimbinkimbi ze-silicon photonic, okuvame kakhulu ukuxhumana kwedatha. Lokhu kuhlanganisa ukuxhumana kwedijithali okunomkhawulokudonsa ophezulu wezinhlelo zokusebenza zebanga elifushane, izikimu eziyinkimbinkimbi zokumodula kwezinhlelo zokusebenza zamabanga amade, nokuxhumana okuhambisanayo. Ngaphezu kokuxhumana kwedatha, inani elikhulu lezinhlelo zokusebenza ezintsha zalobu buchwepheshe ziyahlolwa kokubili kwezamabhizinisi nasezifundweni. Lezi zinhlelo zokusebenza zifaka: I-Nanophotonics (i-nano opto-mechanics) kanye ne-condensed matter physics, i-biosensing, i-nonlinear optics, izinhlelo ze-LiDAR, i-optical gyroscopes, i-RF ehlanganisiweoptoelectronics, ama-transceivers omsakazo ahlanganisiwe, ukuxhumana okuhambisanayo, okushaimithombo yokukhanya, ukuncishiswa komsindo we-laser, izinzwa zegesi, ama-photonics ahlanganisiwe we-wavelength ende, isivinini esikhulu kanye nokucubungula isignali ye-microwave, njll. Izindawo ezithembisayo ikakhulukazi zihlanganisa i-biosensing, imaging, lidar, sensing inertial, hybrid photonic-radio frequency integrated circuits (RFics), nesiginali. ukucubungula.
