Leseli le ata ka har'a z-axis le lebala la motlakase le sebetsa ho x-axis. Li-coefficients tsa electro-optic tsa LiNbO3 ke: r33 = 32 pm / V, r31 = 10 pm / V, r22 = 6.8 pm / V ka lebelo le tlaase le r33 = 31 pm / V, r31 = 8.6 pm / V, r22 = 3.4 pm/V ka maqhubu a phahameng a motlakase. Half-wave voltage: Vπ=λd/(2no3r22L), rc=(ne/no)3r33-r13.LiNbO3 hape ke kristale e ntle ea acousto-optic mme e sebelisoa bakeng sa sephaphatha sa acoustic wave (SAW) le AO modulators. CASTECH e fana ka likristale tsa li-acoustic (SAW) tsa LiNbO3 ka li-wafers, li-boules tse sehiloeng, likarolo tse felileng le lintho tse entsoeng ka tloaelo.
