3 nti 4 nti 6 nti LiNbO3 Wafer Substrate Ib qho khoom siv siv lead ua ke
Cov Ntaub Ntawv Qhia Txog
Cov siv lead ua lithium niobate muaj cov khoom siv electro-optic, acoustooptic, piezoelectric thiab nonlinear zoo heev. Cov siv lead ua lithium niobate yog ib qho tseem ceeb ntawm cov siv lead ua multifunctional nrog cov khoom siv optical zoo nonlinear thiab cov coefficient optical loj nonlinear. Ntxiv mus, kev sib phim theem tsis tseem ceeb tuaj yeem ua tiav. Ua ib qho siv lead ua electro-optical, nws tau siv ua cov khoom siv optical waveguide tseem ceeb. Ua ib qho siv lead ua piezoelectric, nws tuaj yeem siv rau hauv kev tsim cov lim dej SAW zaus tsawg, cov transducers ultrasonic uas tiv taus kub thiab lwm yam. Cov khoom siv lithium niobate doped kuj siv dav. Mg:LN tuaj yeem txhim kho qhov kev puas tsuaj ntawm laser, thiab txhawb kev siv cov siv lead ua lithium niobate hauv kev siv nonlinear optics. Nd:Mg:LN siv lead ua, tuaj yeem ua tiav qhov cuam tshuam tus kheej ob npaug; Fe:LN siv lead ua tuaj yeem siv rau kev khaws cia holographic hauv cov ntim optical.
