Ulwazi Oluningiliziwe
Amakristalu e-Lithium niobate anezakhiwo ezinhle kakhulu ze-electro-optic, acoustooptic, piezoelectric kanye ne-nonlinear. Ikristalu ye-lithium niobate iyikristalu ebalulekile esebenza ngezinto eziningi enezindawo ezinhle zokubona ezingaqondile kanye ne-coefficient enkulu ye-optical nonlinear. Ngaphezu kwalokho, ukufaniswa kwesigaba okungabalulekile kungenziwa. Njengekristalu ye-electro-optical, isetshenziswe njengento ebalulekile ye-optical waveguide. Njengekristalu ye-piezoelectric, ingasetshenziswa ekukhiqizeni izihlungi eziphansi ze-SAW ze-SAW, amandla aphezulu ama-transducers we-ultrasonic angamelana nokushisa okuphezulu nokunye. Izinto ezisetshenziswayo ze-lithium niobate nazo zisetshenziswa kabanzi. I-Mg:LN ingathuthukisa kakhulu umkhawulo womonakalo we-anti-laser, futhi ikhuthaze ukusetshenziswa kwamakristalu e-lithium niobate emkhakheni we-nonlinear optics. I-Nd:Mg:LN crystal, ingafinyelela umphumela wokuziphinda kabili; I-Fe:Amakristalu e-LN angasetshenziselwa ukugcinwa kwe-holographic ngamavolumu abonakalayo.
