论文摘要
Niobate锂（Linbo $ _3 $）是一种具有高机电耦合系数的压电晶体。声学和声学调制过滤器的发育和微型化主要基于各向异性晶体中的表面声波（SAW）和散装波传播，例如Linbo $ _3 $，lithium tantalate和Quartz）。它有可能用于纳米级声学。压电材料的机械性能取决于化学成分和晶体生长条件。这些出色的特征是由于高二阶光声非线性引起的，宽带光谱中的损失较低。
Lithium Niobate (LiNbO$_3$) is a piezoelectric crystal with a high electromechanical coupling coefficient. The development and miniaturization of acousto-electronics, and acousto-optics modulation filters, are primarily based on surface acoustic waves (SAWs) and bulk wave propagation in anisotropic crystals, such as LiNbO$_3$, Lithium Tantalate, and Quartz). It has the potential to be used in nanoscale acoustics. The mechanical properties of the piezoelectric materials depend on the chemical compositions and crystal growth conditions. These excellent features are due to higher second-order optoacoustic nonlinearity with low losses in the broadband spectrum.
