Papiso ea litsamaiso tsa lisebelisoa tsa potoloho tsa photonic
Setšoantšo sa 1 se bontša papiso ea mekhoa e 'meli ea lisebelisoa, indium Phosphorus (InP) le silicon (Si). Ho haella ha indium ho etsa hore InP e be thepa e turang ho feta Si. Hobane li-circuits tse thehiloeng ho silicon li kenyelletsa kholo e nyane ea epitaxial, lihlahisoa tsa li-circuits tse thehiloeng ho silicon hangata li phahame ho feta tsa li-circuits tsa InP. Lipotolohong tse thehiloeng ho silicon, germanium (Ge), eo hangata e sebelisoang feela hoPhotodetector(lisebelisoa tsa leseli), e hloka kholo ea epitaxial, ha e ntse e le lits'ebetsong tsa InP, esita le li-waveguides tse sa sebetseng li tlameha ho lokisoa ke kholo ea epitaxial. Khōlo ea Epitaxial e atisa ho ba le sekoli se phahameng ho feta khōlo e le 'ngoe ea kristale, joalo ka ho tloha ho ingot ea kristale. Li-waveguides tsa InP li na le phapang e phahameng ea li-index tse fapaneng feela, ha li-waveguide tse thehiloeng ka silicon li na le phapang e phahameng ea li-refractive index ka bobeli ba transverse le longitudinal, e lumellang lisebelisoa tse thehiloeng ho silicon ho fihlela radii e nyane e kobehang le meaho e meng e kopaneng. InGaAsP e na le lekhalo le tobileng la sehlopha, ha Si le Ge ba sa etse joalo. Ka lebaka leo, litsamaiso tsa thepa tsa InP li phahame ho latela ts'ebetso ea laser. Li-oxide tsa ka hare tsa tsamaiso ea InP ha li tsitsitse ebile li tiile joaloka li-oxide tsa ka hare tsa Si, silicon dioxide (SiO2). Silicon ke thepa e matla ho feta InP, e lumellang ts'ebeliso ea boholo bo boholo ba wafer, ke hore ho tloha ho 300 mm (haufinyane e tla ntlafatsoa ho 450 mm) ha e bapisoa le 75 mm ho InP. InPli-modulatorshangata e ipapisitse le phello ea quantum-confined Stark, e sa rateheng mocheso ka lebaka la ho sisinyeha ha sehlopha ho bakoang ke mocheso. Ka lehlakoreng le leng, ho itšetleha ka mocheso oa li-modulator tse thehiloeng ho silicon ho nyane haholo.

Theknoloji ea silicon photonics ka kakaretso e nkoa e loketse feela lihlahisoa tse theko e tlaase, tse khutšoanyane, tse phahameng (likotoana tse fetang limilione tse 1 ka selemo). Sena ke hobane ho amohetsoe ke batho ba bangata hore ho hlokahala palo e kholo ea matla a li-wafer ho hasanya mask le litšenyehelo tsa nts'etsopele, le horetheknoloji ea silicon photonicse na le mefokolo e kholo ea ts'ebetso lits'ebetsong tsa libaka tsa toropo-to-toropo le lits'ebetso tsa lihlahisoa tsa nako e telele. Leha ho le joalo, ha e le hantle, se fapaneng ke 'nete. Ka lisebelisoa tse theko e tlase, tse khutšoane, tse fanang ka chai e ngata, laser ea vertical cavity surface-emitting laser (VCSEL) lelaser-modulated ka ho toba (Laser ea DML) : Laser e fetotsoeng ka ho toba e baka khatello e kholo ea tlhōlisano, 'me bofokoli ba theknoloji ea silicon-based photonic e ke keng ea kopanya lasers habonolo e fetohile bothata bo boholo. Ka lehlakoreng le leng, ho metro, lits'ebetso tsa nako e telele, ka lebaka la khetho ea ho kopanya theknoloji ea silicon photonics le digital signal processing (DSP) hammoho (eo hangata e leng libakeng tsa mocheso o phahameng), ho molemo ho arola laser. Ho phaella moo, theknoloji ea ho lemoha e lumellanang e ka etsa hore ho be le mefokolo ea theknoloji ea silicon photonics ka tekanyo e kholo, e kang bothata ba hore nako e lefifi e nyenyane haholo ho feta photocurrent ea oscillator ea sebakeng seo. Ka nako e ts'oanang, ho boetse ho fosahetse ho nahana hore ho hlokahala palo e kholo ea matla a liphaephe ho koahela litšenyehelo tsa mask le nts'etsopele, hobane theknoloji ea silicon photonics e sebelisa boholo ba li-node tse kholo haholo ho feta tse tsoetseng pele ka ho fetisisa tse tlatsanang le lisebelisoa tsa tšepe tsa oxide semiconductors (CMOS), kahoo limaske tse hlokahalang le tlhahiso ea lihlahisoa li batla li le theko e tlaase.
