Lithium Niobate (LN) crystal yana da babban polarization na kwatsam (0.70 C/m)2 a dakin da zafin jiki) kuma kristal ne na ferroelectric tare da mafi girman zafin jiki na Curie (1210 ℃) samu zuwa yanzu. LN crystal yana da halaye guda biyu waɗanda ke jawo hankali na musamman. Na farko, yana da yawa super photoelectric effects, ciki har da piezoelectric sakamako, electro-optic sakamako, nonlinear Tantancewar sakamako, photorefractive sakamako, photovoltaic sakamako, photoelastic sakamako, acoustooptic sakamako da sauran photoelectric Properties. Na biyu, aikin LN crystal yana daidaitawa sosai, wanda ke haifar da tsarin lattice da kuma tsarin lahani mai yawa na LN crystal. Yawancin kaddarorin kristal na LN ana iya daidaita su sosai ta hanyar abun da ke ciki na crystal, sinadarin doping, sarrafa jihar valence da sauransu. Bugu da ƙari, kristal LN yana da wadata a cikin kayan aiki, wanda ke nufin babban inganci da girman girman kristal guda ɗaya yana da sauƙin shiryawa.
LN crystal yana da barga na zahiri da sinadarai, mai sauƙin sarrafawa, kewayon watsa haske mai faɗi (0.3 ~ 5μm), kuma yana da babban birefringence (kimanin 0.8 @ 633 nm) , kuma mai sauƙin sanya shi ya zama jagorar igiyar gani mai inganci. Sabili da haka, na'urorin optoelectronic na tushen LN, misali mai tacewa acoustic kalaman tacewa, mai canza haske, lokaci modulator, mai keɓancewa na gani, electro-optic Q-switch (www.wisoptic.com), ana nazarin ko'ina kuma ana amfani da su zuwa filayen masu zuwa: fasahar lantarki. , Fasahar sadarwa ta gani, fasahar Laser. Kwanan nan, tare da nasarorin da aka samu a cikin aikace-aikacen 5G, micro/nano photonics, hadedde photonics da adadi mai yawa, lu'ulu'u na LN sun sake jawo hankali sosai. A cikin 2017, Burrows na Jami'ar Harvard har ma ya ba da shawarar cewa zamanin“kwarin lithium niobate” yanzu yana zuwa.
