A makwaara Lithium niobate dị ka silikọn optical. E nwere ilu na-ekwu na "lithium niobate bụ maka nkwukọrịta anya ihe silikọn bụ nye semiconductors." Mkpa silikọn dị na mgbanwe eletrọniki, yabụ gịnị mere ụlọ ọrụ ji enwe olileanya maka ihe ndị dị na lithium niobate?
A maara Lithium niobate (LiNbO3) dị ka "silikọn anya" n'ụlọ ọrụ mmepụta ihe. Na mgbakwunye na uru eke dịka ezigbo nkwụsi ike anụ ahụ na kemịkalụ, windo sara mbara nke na-enwu enwu (0.4m ~ 5m), na nnukwu ọnụọgụ electro-optical (33 = 27 pm/V), lithium niobate bụkwa ụdị kristal nwere ọtụtụ isi mmalite ihe eji emepụta ihe na ọnụ ahịa dị ala. A na-ejikarị ya eme ihe na nzacha arụmọrụ dị elu, ngwaọrụ electro-optical, nchekwa holographic, ngosipụta holographic 3D, ngwaọrụ anya na-abụghị ahịrị, nkwukọrịta quantum anya na ndị ọzọ. N'ọhịa nkwukọrịta anya, lithium niobate na-arụ ọrụ nke modulation ìhè, ọ ghọwokwa ngwaahịa bụ isi na modulator electro-optical dị elu ugbu a (Eo Modulator) ahịa.
Ugbu a, e nwere teknụzụ atọ bụ isi maka mgbanwe ọkụ na ụlọ ọrụ ahụ: electro-optical modulators (Eo Modulator) dabere na ìhè silicon, indium phosphide nalithium niobatenyiwe ihe eji arụ ọrụ. A na-ejikarị silicon optical modulator eme ihe na modulu transceiver data dị mkpụmkpụ, a na-ejikarị indium phosphide modulator eme ihe na modulu transceiver network optical dị n'etiti na ogologo oge, a na-ejikwa lithium niobate electro-optical modulator (Eo Modulator) eme ihe na nkwukọrịta netwọk dị n'azụ azụ na ebe data dị elu nke otu ebili mmiri 100/200Gbps. N'ime nyiwe ihe modulator atọ dị n'elu, modulator lithium niobate dị gịrịgịrị nke apụtala n'afọ ndị na-adịbeghị anya nwere uru bandwit nke ihe ndị ọzọ na-enweghị ike ịha nhata.
Lithium niobate bụ ụdị ihe na-adịghị n'ime ahụ, usoro kemịkalụLiNbO3, bụ kristal na-adịghị mma, kristal ferroelectric, kristal lithium niobate polarized nwere piezoelectric, ferroelectric, photoelectric, optics na-abụghị ahịrị, thermoelectric na ihe ndị ọzọ dị na ihe ahụ, n'otu oge ahụ yana mmetụta photorefractive. kristal lithium niobate bụ otu n'ime ihe ọhụrụ inorganic kachasị eji eme ihe, ọ bụ ezigbo ihe mgbanwe ike piezoelectric, ihe ferroelectric, ihe electro-optical, lithium niobate dị ka ihe electro-optical na nkwukọrịta anya na-arụ ọrụ na mgbanwe ìhè.
Ihe lithium niobate, nke a maara dị ka "silikọn anya", na-eji usoro micro-nano kachasị ọhụrụ iji kpoo oyi akwa silicon dioxide (SiO2) na silicon substrate, jikọta ihe mkpuchi lithium niobate na okpomọkụ dị elu iji wuo elu nkewa, wee mechaa wepụ ihe nkiri lithium niobate. Ihe modulator lithium niobate dị gịrịgịrị nke a kwadebere nwere uru nke arụmọrụ dị elu, ọnụ ala dị ala, obere nha, mmepụta oke, na ndakọrịta na teknụzụ CMOS, ọ bụkwa ngwọta asọmpi maka njikọ anya dị elu n'ọdịnihu.
Ọ bụrụ na aha etiti mgbanwe eletrọniki bụ aha ihe silicon mere ka o kwe omume, mgbe ahụ mgbanwe fotonics nwere ike ịpụta na ihe lithium niobate, nke a maara dị ka "silicon anya" lithium niobate bụ ihe na-enweghị agba nke na-ejikọta mmetụta fotorefractive, mmetụta na-abụghị ahịrị, mmetụta electro-optical, mmetụta acousto-optical, mmetụta piezoelectric na mmetụta okpomọkụ.
