Lithium niobate e boetse e tsejoa e le optical silicon. 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 lisebelisoa tsa elektroniki, joale ke eng e etsang hore indasteri e be le tšepo e kaalo ka thepa ea lithium niobate?
Lithium niobate (LiNbO3) e tsejoa e le "silicon ea optical" indastering. Ntle le melemo ea tlhaho e kang botsitso bo botle ba 'mele le lik'hemik'hale, fensetere e pharaletseng e bonaletsang ka mahlo (0.4m ~ 5m), le coefficient e kholo ea electro-optical (33 = 27 pm/V), lithium niobate le eona ke mofuta oa kristale e nang le mehloli e mengata ea thepa e tala le theko e tlase. E sebelisoa haholo lifilthareng tse sebetsang hantle, lisebelisoa tsa electro-optical, polokelo ea holographic, ponts'o ea holographic ea 3D, lisebelisoa tsa optical tse seng tsa linear, puisano ea quantum ea optical le tse ling. Lefapheng la puisano ea optical, lithium niobate e bapala karolo ea ho fetola leseli haholo, 'me e fetohile sehlahisoa se seholo ho modulator ea electro-optical ea hona joale e potlakileng haholo (Modulator ea Eo) 'maraka.
Hona jwale, ho na le ditheknoloji tse tharo tse ka sehloohong bakeng sa ho fetolwa ha lesedi indastering: di-modulator tsa electro-optical (Eo Modulator) tse thehilweng hodima lesedi la silicon, indium phosphide lelithium niobateliforomo tsa thepa. Modulatara wa Silicon optical o sebediswa haholoholo di-moduleng tsa transceiver tsa puisano ya data tsa nako e kgutshwane, modulatara wa indium phosphide o sebediswa haholoholo di-moduleng tsa transceiver tsa netweke ya puisano ya optical ya nako e mahareng le e telele, mme modulatara wa electro-optical wa lithium niobate (Eo Modulator) o sebediswa haholoholo dipuisanong tse kopaneng tsa netweke ya mokokotlo e telele le ditsing tsa data tsa lebelo le le leng la 100/200Gbps. Har'a di-platform tse tharo tse ka hodimo tsa modulatara wa lebelo le phahameng, modulatara wa filimi e tshesane ya lithium niobate o hlahileng dilemong tsa morao tjena o na le monyetla wa bandwidth oo disebediswa tse ding di ke keng tsa o bapisa.
Lithium niobate ke mofuta oa ntho e sa pheleng, mokhoa oa lik'hemik'haleLiNbO3, ke kristale e mpe, kristale ea ferroelectric, kristale ea lithium niobate e nang le piezoelectric, ferroelectric, photoelectric, nonlinear optics, thermoelectric le thepa e meng ea thepa, ka nako e le 'ngoe e nang le phello ea photorefractive. Kristale ea lithium niobate ke e 'ngoe ea thepa e ncha e sa tloaelehang e sebelisoang haholo, ke thepa e ntle ea phapanyetsano ea matla a piezoelectric, thepa ea ferroelectric, thepa ea electro-optical, lithium niobate e le thepa ea electro-optical puisanong ea optical e bapala karolo ho feto-fetoheng ha leseli.
Thepa ea lithium niobate, e tsejoang e le "silicon ea optical", e sebelisa mokhoa oa morao-rao oa micro-nano ho steamer lera la silicon dioxide (SiO2) holim'a substrate ea silicon, ho kopanya substrate ea lithium niobate mochesong o phahameng ho haha bokaholimo ba karohano, 'me qetellong ho tlosa filimi ea lithium niobate. Modulator ea lithium niobate ea filimi e tšesaane e lokisitsoeng e na le melemo ea ts'ebetso e phahameng, litšenyehelo tse tlase, boholo bo bonyenyane, tlhahiso ea bongata, le ho lumellana le theknoloji ea CMOS, 'me ke tharollo ea tlholisano bakeng sa khokahano ea optical e potlakileng nakong e tlang.
Haeba setsi sa phetoho ea elektronike se reheletsoe ka thepa ea silicon e entseng hore e khonehe, joale phetoho ea photonics e ka lateloa ke thepa ea lithium niobate, e tsejoang e le "silicon ea optical" lithium niobate ke thepa e bonaletsang e se nang 'mala e kopanyang litlamorao tsa photorefractive, litlamorao tse seng tsa linear, litlamorao tsa electro-optical, litlamorao tsa acousto-optical, litlamorao tsa piezoelectric le litlamorao tsa mocheso. Bongata ba thepa ea eona e ka laoloa ke motsoako oa kristale, doping ea element, taolo ea boemo ba valence le lintlha tse ling. E sebelisoa haholo ho lokisa tataiso ea maqhubu a optical, switch ea optical, modulator ea piezoelectric,modulator ea electro-optical, jenereithara ea bobeli ea harmonic, sesebelisoa sa ho atisa maqhubu a laser le lihlahisoa tse ling. Indastering ea puisano ea optical, li-modulator ke 'maraka oa bohlokoa oa ts'ebeliso bakeng sa lithium niobate.
