Abstract
Recently, metallic nanowires have been applied in various applications such as plasmonics and nanoelectronics. To construct nanodevices using metallic nanowires, manipulation and fixation techniques of nanowires are indispensable. Here, we proposed a novel method for two-dimensional manipulation and fixation of a metallic nanowires using dual-beam optical trap. By irradiating dual beams to both ends of a metallic nanowire, the metallic nanowire can be trapped between the Gaussian beams due to gradient force. Then, by increasing the laser power, the metallic nanowire is fixed on the substrate due to aggregation of metallic nanoparticles containing the sample solution. In this study, we examined the optical radiation pressure exerted on a metallic nanowire by electromagnetic field analysis. We demonstrated the attitude control and fixation of metallic nanowires using dual-beam optical trap.
