Abstract
Recently practical micro/nano devices using nanomaterials such as nanoparticles and nanowires have actively developed in various fields including nanophotonics and nanoelectronics. Manipulation of nanowires is indispensable for constructing the microdevices. Here we demonstrate the rotation and translation of a silver nanowire by an optical vortex. In our method, a silver nanowire can be grasped and rotated by repulsive force of an optical vortex. In addition, by switching the direction of azimuthal phase shift repetitively, a silver nanowire can be aligned in any direction. By moving the stage supporting a sample, the nanowire can be also translated to the desired position with the fixed posture. The manipulation technique using an optical vortex will be a powerful tool for manipulating and assembling various kinds of nanowires.
