Year: 2013
Type: conference-paper
Abstract: Recently practical micro/nano devices using nanomaterials such as nanoparticles and nanowires have been developed in various fields including nanophotonics and nanoelectronics. Manipulation of nanowires is indispensable for constructing the microdevices. Here we propose and experimentally demonstrate a novel method of three-dimensional optical manipulation of a metallic nanowire using an optical vortex. In our method, a metallic nanowire can be grasped by optical repulsive force and simultaneously rotated by total angular momentum of an optical vortex. In addition, the posture of a metallic nanowire can be horizontally or vertically fixed in any direction by high-speed switching of the helical phase shift of an optical vortex. The aligned nanowire can be translated to the desired position by moving the stage supporting a sample.
