Lithium Niobate (LN) kristal nwere nnukwu polarization na-akpaghị aka (0.70 C/m).2 na ime ụlọ) na ọ bụ kristal ferroelectric nke nwere okpomọkụ Curie kachasị elu (1210 ℃) hụrụ ugbu a. kristal LN nwere njirimara abụọ na-adọta nlebara anya pụrụ iche. Nke mbụ, ọ nwere ọtụtụ mmetụta fotoelectric dị oke egwu, gụnyere mmetụta piezoelectric, mmetụta electro-optic, mmetụta anya na-adịghị ahụ anya, mmetụta fotorefractive, mmetụta fotovoltaic, mmetụta fotoelastic, mmetụta acoustooptic na ihe ndị ọzọ fotoelectric. Nke abụọ, arụ ọrụ nke kristal LN na-agbanwe nke ukwuu, nke a na-eme site na nhazi nke lattice na nrụrụ dị ukwuu nke kristal LN. Enwere ike ịhazi ọtụtụ ihe nke kristal LN site na nhazi kristal, mmewere doping, njikwa steeti valence na ihe ndị ọzọ. Na mgbakwunye, kristal LN bara ụba na akụrụngwa akụrụngwa, nke pụtara ịdị mma na nnukwu otu kristal dị mfe ịkwadebe.
kristal LN nwere akụrụngwa anụ ahụ na kemịkalụ kwụsiri ike, dị mfe ịhazi, oke nnyefe ọkụ obosara (0.3 ~ 5μm), ma nwee nnukwu birefringence (ihe dịka 0.8 @ 633 nm) , ma dị mfe ịme ka ọ bụrụ ntuziaka ebili mmiri dị elu. Ya mere, ngwaọrụ optoelectronic dabeere na LN, dịka nzacha ụda ụda elu, modulator ọkụ, modulator oge, anya isolator, electro-optic Q-switch (www.wisoptic.com), na-amụkarị ma tinye ya n'ọrụ na mpaghara ndị a: teknụzụ eletrọnịkị. , Optical Communication technology, laser technology. N'oge na-adịbeghị anya, site na ọganihu na ntinye nke 5G, micro/nano photonics, agbakwunyere photonics na quantum optics, kristal LN adọtala mmasị ọzọ. Na 2017, Burrows nke Mahadum Harvard ọbụna tụrụ aro na oge nke“lithium niobate ndagwurugwu” na-abịa ugbu a.
