Light-Assisted Assembly and Reconfiguration of Complex Optical Materials using Microphotonic Templates

Abstract

In this work, we successfully proposed and demonstrated a new method for making ordered arrays of nanoparticles. The technique uses a template made of silicon with small holes in it. Shining laser light at the template creates a strong optical field in the holes; these then serve as optical traps. By designing the template appropriately, we can assemble ordered arrays of dielectric or gold nanoparticles. Changing the laser wavelength allows the pattern of traps, and thus particles, to be reconfigured.
