Lithium niobate e boetse e tsejoa e le silicon ea optical. Ho na le polelo e reng "lithium niobate ke puisano ea optical seo silicon e leng sona ho li-semiconductors." Bohlokoa ba silicon phetohong ea elektronike, joale ke eng e etsang hore indasteri e be le tšepo ka thepa ea lithium niobate?
Lithium niobate (LiNbO3) e tsejoa e le "silicon optical" indastering. Ntle le melemo ea tlhaho joalo ka botsitso ba 'mele le lik'hemik'hale, fensetere e pepeneneng ka bophara (0.4m ~ 5m), le coefficient e kholo ea electro-optical (33 = 27 pm/V), lithium niobate le eona ke mofuta oa kristale e tala e tala. mehloli ea lintho tse bonahalang le theko e tlaase. E sebelisoa haholo lits'ebetsong tse phahameng tsa ts'ebetso, lisebelisoa tsa electro-optical, polokelo ea holographic, pontšo ea holographic ea 3D, lisebelisoa tse sa tloaelehang tsa optical, puisano ea optical quantum joalo-joalo. Sebakeng sa puisano ea optical, lithium niobate haholo-holo e bapala karolo ea ho feto-fetoha ha leseli, 'me e fetohile sehlahisoa se ka sehloohong ho modulator ea hona joale ea lebelo le phahameng la motlakase (Eo Modulator) marakeng.
Hajoale, ho na le mahlale a mararo a mantlha a ho feto-fetoha ha leseli indastering: li-electro-optical modulator (Eo Modulator) tse ipapisitseng le leseli la silicon, indium phosphide le.lithium niobatesethala sa lintho tse bonahalang. Silicon optical modulator e sebelisoa haholo ho li-module tsa transceiver tsa data tsa nako e khuts'oane, modulator ea indium phosphide e sebelisoa haholo ho li-transceiver tsa marang-rang a mahareng le a malelele, 'me lithium niobate electro-optical modulator (Eo Modulator) e sebelisoa haholo puisano e tsitsitseng ea mokokotlo oa mokokotlo oa nako e telele le litsi tsa data tse nang le maqhubu a le mong 100/200Gbps. Har'a li-platform tse tharo tse ka holimo tsa li-ultra-high speed modulator, filimi e tšesaane ea lithium niobate modulator e hlahileng lilemong tsa morao tjena e na le molemo oa bandwidth oo lisebelisoa tse ling li ke keng tsa li bapisa.
Lithium niobate ke mofuta oa ntho e sa tloaelehang, foromo ea lik'hemik'haleLiNbO3, ke kristale e mpe, kristale ea ferroelectric, polarized lithium niobate crystal e nang le piezoelectric, ferroelectric, photoelectric, nonlinear optics, thermoelectric le lisebelisoa tse ling tsa thepa, ka nako e ts'oanang le phello ea photorefractive. Lithium niobate crystal ke e 'ngoe ea lisebelisoa tse ncha tse sebelisoang ka ho fetisisa tse sebelisoang ka ho fetisisa, ke thepa e ntle ea phapanyetsano ea matla a piezoelectric, thepa ea ferroelectric, electro-optical material, lithium niobate e le lisebelisoa tsa electro-optical puisanong ea optical e phetha karolo ea ho feto-fetoha ha leseli.
Thepa ea lithium niobate, e tsejoang e le "silicon optical", e sebelisa mokhoa oa morao-rao oa micro-nano ho chesa lera la silicon dioxide (SiO2) holim'a silicon substrate, e tlama karoloana ea lithium niobate ka mocheso o phahameng ho haha sebaka sa ho phunyeha, 'me qetellong e peel. ho tloha filimi ea lithium niobate. Filimi e nyenyane e lokiselitsoeng ea lithium niobate modulator e na le melemo ea ts'ebetso e phahameng, theko e tlaase, boholo bo nyane, tlhahiso ea bongata, le ho lumellana le theknoloji ea CMOS, 'me ke tharollo ea tlhōlisano bakeng sa ho hokahanya ha optical ka lebelo le phahameng nakong e tlang.
Haeba setsi sa phetoho ea elektronike se bitsoa ka thepa ea silicon e entseng hore e khonehe, joale phetoho ea photonics e ka 'na ea lateloa ke lintho tse bonahalang lithium niobate, tse tsejoang e le "optical silicon" lithium niobate ke ntho e se nang mebala e hlakileng e kopanyang liphello tsa photorefractive, nonlinear. liphello, liphello tsa electro-optical, liphello tsa acousto-optical, liphello tsa piezoelectric le liphello tsa mocheso. Boholo ba thepa ea eona e ka laoloa ke sebopeho sa kristale, doping ea element, taolo ea boemo ba valence le lintlha tse ling. E sebelisoa haholo ho lokisa waveguide ea optical, switch optical, modulator ea piezoelectric,motlakase oa motlakase, jenereithara ea bobeli ea harmonic, laser frequency multiplier le lihlahisoa tse ling.
