Ikristalu ye-Lithium Niobate (LN) ine-polarization ephezulu ezenzakalelayo (0.70 C/m² ezingeni lokushisa legumbi) futhi iyikristalu ye-ferroelectric enezinga lokushisa eliphakeme kakhulu le-Curie (1210 ℃) kutholwe kuze kube manje. I-LN crystal inezici ezimbili eziheha ukunakwa okukhethekile. Okokuqala, inemiphumela eminingi ye-super photoelectric, okuhlanganisa umphumela we-piezoelectric, umphumela we-electro-optic, umphumela we-optical nonlinear, umphumela we-photorefractive, umphumela we-photovoltaic, umphumela we-photoelastic, umphumela we-acoustooptic nezinye izakhiwo ze-photoelectric. Okwesibili, ukusebenza kwe-LN crystal kuguqulwa kakhulu, okubangelwa ukwakheka kwe-lattice kanye nesakhiwo esinesici esiningi se-LN crystal. Izakhiwo eziningi ze-LN crystal zingalawulwa kakhulu ngokubunjwa kwekristalu, i-doping element, ukulawulwa kwesimo se-valence nokunye. Ngaphezu kwalokho, ikristalu ye-LN inothile ngezinto ezingavuthiwe, okusho ukuthi ikristalu eyodwa yekhwalithi ephezulu nosayizi omkhulu kulula ukuyilungisa.

Ikristalu ye-LN inezinto ezinzile ngokomzimba namakhemikhali, kulula ukusetshenzwa, ububanzi bokudlulisa ukukhanya (0.3 ~5μm), futhi ine-birefringence enkulu (cishe 0.8 @ 633 nm) , futhi kulula ukwenziwa ibe yikhwalithi ephezulu ye-optical waveguide. Ngakho-ke, imishini ye-optoelectronic esekelwe ku-LN, isb isihlungi se-surface acoustic wave, imoduli yokukhanya, imodulator yesigaba, i-optical isolator, i-electro-optic Q-switch (www.wisoptic.com), ifundwa kabanzi futhi isetshenziswa kule mikhakha elandelayo: ubuchwepheshe be-elekthronikhi. , ubuchwepheshe bokuxhumana obubonakalayo, ubuchwepheshe be-laser. Muva nje, ngokuphumelela ekusetshenzisweni kwe-5G, i-micro/nano photonics, i-photonics ehlanganisiwe ne-quantum optics, amakristalu e-LN adonse ukunaka okubanzi futhi. Ngo-2017, uBurrows waseHarvard University waze waphakamisa ukuthi inkathi ye“i-lithium niobate valley” iyeza manje.
