Paper Abstract

Complex 3D nanophotonic devices demand robust methods for the design and rapid prototyping of heterogeneous material structures with sub-100 nm resolution. Here we present an automated optical tweezer platform for assembling nanoparticles of multiple materials. In pursuit of higher throughput, we have demonstrated record nanoparticle manipulation speeds >150 um/s. To design structures, we use a coupled dipole model that is orders of magnitude faster than commercial tools. In developing this method, we have found that a longstanding practice of basing a metallic nanoparticle’s dipole moment on its skin depth is significantly less accurate than calculations based on full particle volume.
