Theknoloji ea silicon photonics

Ha ts'ebetso ea chip e ntse e fokotseha butle-butle, litlamorao tse fapaneng tse bakoang ke khokahano e fetoha ntlha ea bohlokoa e amang ts'ebetso ea chip. Khokahano ea chip ke e 'ngoe ea litšitiso tsa tekheniki tsa hajoale, 'me theknoloji ea optoelectronics e thehiloeng ho silicon e ka rarolla bothata bona. Theknoloji ea silicon photonic ke sesebelisoa sa hopuisano ea mahlotheknoloji e sebelisang lehlaseli la laser ho fapana le lets'oao la semiconductor la elektroniki ho fetisa data. Ke theknoloji ea moloko o mocha e thehiloeng holim'a thepa ea substrate e thehiloeng ho silicon le silicon 'me e sebelisa ts'ebetso e teng ea CMOS bakeng sasesebelisoa sa opticalnts'etsopele le kopanyo. Molemo oa eona o moholo ke hore e na le sekhahla se phahameng haholo sa phetiso, e leng se ka etsang hore lebelo la phetiso ea data lipakeng tsa li-core tsa processor le potlake ka makhetlo a 100 kapa ho feta, 'me bokhoni ba matla le bona bo phahame haholo, kahoo e nkoa e le moloko o mocha oa theknoloji ea semiconductor.

Ho tloha khale, difotoniki tsa silicon di se di hlahisitswe ho SOI, empa di-wafer tsa SOI di theko e boima mme ha se hakaalo hore ke thepa e ntle ka ho fetisisa bakeng sa mesebetsi yohle e fapaneng ya difotoniki. Ka nako e ts'oanang, ha ditefiso tsa data di ntse di eketseha, ho fetolwa ha lebelo le phahameng ha disebediswa tsa silicon ho ntse ho fetoha bothata, kahoo mefuta e fapaneng ya disebediswa tse ntjha tse kang difilimi tsa LNO, InP, BTO, di-polymer le disebediswa tsa plasma di se di hlahisitswe ho fihlella tshebetso e phahameng.

Bokhoni bo boholo ba silicon photonics bo lutse ho kopanyeng mesebetsi e mengata ka har'a sephutheloana se le seng le ho hlahisa boholo ba eona kapa kaofela ha eona, e le karolo ea chip e le 'ngoe kapa sehlopha sa li-chip, ho sebelisoa lisebelisoa tse tšoanang tsa tlhahiso tse sebelisoang ho haha ​​​​lisebelisoa tse tsoetseng pele tsa microelectronic (sheba Setšoantšo sa 3). Ho etsa joalo ho tla fokotsa haholo litšenyehelo tsa ho fetisa data ho fetalikhoele tsa mahlole ho theha menyetla bakeng sa mefuta e fapaneng ya ditshebediso tse ntjha tse kgolo holitšoantšo, e lumellang kaho ea litsamaiso tse rarahaneng haholo ka theko e tlase haholo.

Likopo tse ngata lia hlaha bakeng sa litsamaiso tse rarahaneng tsa photonic tsa silicon, tse atileng haholo ke puisano ea data. Sena se kenyelletsa puisano ea dijithale ea bandwidth e phahameng bakeng sa lits'ebetso tsa nako e khuts'oane, merero e rarahaneng ea modulation bakeng sa lits'ebetso tsa hole, le puisano e kopaneng. Ntle le puisano ea data, palo e kholo ea lits'ebetso tse ncha tsa theknoloji ena e ntse e hlahlojoa khoebong le thutong. Likopo tsena li kenyelletsa: Nanophotonics (nano opto-mechanics) le fisiks ea matter e kopantseng, biosensing, nonlinear optics, litsamaiso tsa LiDAR, optical gyroscopes, RF e kopantsoeng.lisebelisoa tsa optoelectronics, li-transceiver tsa radio tse kopantsoeng, puisano e kopanetsoeng, tse nchamehloli ea leseli, phokotso ea lerata la laser, li-sensor tsa khase, li-photonics tse kopantsoeng tsa bolelele ba wavelength bo bolelele haholo, ts'ebetso ea matšoao a lebelo le phahameng le a microwave, jj. Libaka tse tšepisang haholo li kenyelletsa biosensing, imaging, lidar, inertial sensing, hybrid photonic-radio frequency integrated circuits (RFics), le ts'ebetso ea matšoao.
