我们报告了光学驱动微机械元件的原理证明演示。光角动量从圆偏振激光束转移到限制在光镊陷阱中的双折射粒子。光学扭矩使粒子以高达 350 Hz 的速度旋转,并且利用该扭矩来驱动光学捕获的微加工结构。我们描述了一种用于生产微结构的光刻方法,并展示了如何在微机械系统中使用光驱动电机。 (C) 2001 年美国物理研究所。
We report on a proof of principle demonstration of an optically driven micromachine element. Optical angular momentum is transferred from a circularly polarized laser beam to a birefringent particle confined in an optical tweezers trap. The optical torque causes the particle to spin at up to 350 Hz, and this torque is harnessed to drive an optically trapped microfabricated structure. We describe a photolithographic method for producing the microstructures and show how a light driven motor could be used in a micromachine system. (C) 2001 American Institute of Physics.
