Manipulation and assembly of ZnO nanowires with single holographic optical tweezers system

Jing Li and Gang Du

ZnO nanowires, characterized with high melting points, are hard to assemble together with laser fusion. In order to build micro–nano structures with ZnO nanowires, a polymer film with a low melting point and high optical transparency is introduced as a substrate for ZnO nanowires to be deposited. A holographic optical tweezers system is used not only to manipulate ZnO nanowires, but also to melt the polymer film for the fixation of ZnO nanowires. By this method, micro–nano structures composed of ZnO nanowires are produced, which can be utilized as subwavelength optical waveguides.
