We report on the optical trapping characteristics of InP nanowires with dimensions of 30 (±6) nm in diameter and 2-15 μm in length. We describe a method for calibrating the absolute position of individual nanowires relative to the trapping center using synchronous high-speed position sensing and acousto-optic beam switching. Through brownian dynamics we investigate effects of the laser power and polarization on trap stability, as well as length dependence and the effect of simultaneous trapping multiple nanowires.
我们报告了尺寸为 30（±6）nm 直径和 2-15μm 长度的 InP 纳米线的光阱特性。我们描述了一种使用同步高速位置感应和声光光束切换来校准单个纳米线相对于捕获中心的绝对位置的方法。通过布朗动力学，我们研究了激光功率和偏振对陷阱稳定性的影响，以及长度依赖性和同时捕获多个纳米线的影响。
