Lithium Niobate (LN) crystal imakhala ndi polarization yapamwamba kwambiri (0.70 C/m² pa firiji) ndipo ndi kristalo wa ferroelectric wokhala ndi kutentha kwambiri kwa Curie (1210 ℃) zapezeka mpaka pano. LN crystal ili ndi makhalidwe awiri omwe amakopa chidwi chapadera. Choyamba, ili ndi zotsatira zambiri za photoelectric, kuphatikizapo piezoelectric effect, electro-optic effect, nonlinear optical effect, photorefractive effect, photovoltaic effect, photoelastic effect, acoustooptic effect ndi zina za photoelectric. Chachiwiri, magwiridwe antchito a LN crystal ndi osinthika kwambiri, omwe amayamba chifukwa cha kapangidwe ka lattice komanso mawonekedwe ochulukirapo a LN crystal. Zambiri za LN crystal zimatha kuyendetsedwa kwambiri ndi mawonekedwe a crystal, doping element, control valence state ndi zina zotero. Kuphatikiza apo, kristalo ya LN imakhala ndi zinthu zambiri zopangira, zomwe zikutanthauza kuti kristalo wapamwamba kwambiri komanso yayikulu yayikulu ndiyosavuta kukonzekera.

Krustalo ya LN ili ndi mphamvu zokhazikika zakuthupi ndi zamankhwala, zosavuta kuzikonza, kufalikira kosiyanasiyana (0.3 ~ 5)μm), ndipo ili ndi birefringence yayikulu (pafupifupi 0.8 @ 633 nm), komanso yosavuta kupanga mawonekedwe apamwamba kwambiri opangira mawonekedwe. Chifukwa chake, zida za LN zochokera ku optoelectronic, mwachitsanzo, zosefera zamtundu wamayimbidwe, moduli yowunikira, gawo moduli, optical isolator, electro-optic Q-switch (www.wisoptic.com), zimaphunziridwa kwambiri ndikugwiritsidwa ntchito pazinthu izi: ukadaulo wamagetsi , ukadaulo waukadaulo wolumikizirana, ukadaulo wa laser. Posachedwapa, ndi kupambana pakugwiritsa ntchito 5G, micro/nano photonics, photonics Integrated ndi quantum Optics, makhiristo a LN akopa chidwi kwambiri. Mu 2017, a Burrows aku Harvard University adaganizanso kuti nthawi ya“lithiamu niobate chigwa” ikubwera tsopano.
