中文摘要:本文基于光镊机理与倒置显微成像方法首次成功实现了铌酸锂微晶颗粒的光学捕获控制和光致取向的直接观测。由于铌酸锂微晶具有光学各向异性性质,所以在线偏振飞秒激光的操控下,所捕获的铌酸锂微晶颗粒能够依据激光偏振方向成功实现光控制取向。同时,我们分析了铌酸锂微晶颗粒的激光控制取向机理,本文的研究工作说明铌酸锂微晶颗粒的取向可以利用激光的线性偏振方向进行光致取向旋转。这些结果有望应用于微纳光子学、MEMS、光控微型马达和微操作等科学研究领域。

Optically controlled orientation of lithium niobate micro crystal particle
Abstract:In this work, the experimental system for optically controlled capturing and orientating is designed. Using the system, we demonstrate optically capturing of lithium niobate micro crystal particle. Moreover, the captured particle becomes aligned with the direction of linear polarization. Finally, we present optically controlled orientation theory of lithium niobate crystal particle. The work illustrates that the alignment of lithium niobate micro crystal particles can be optically orientation by the linear polarization’s direction of laser light. These results can be further used in micro sensors, photonics, MEMS, light-induced micro motor, and micro manipulation fields.
