Binding of a pair of Au nanoparticles in a wide Gaussian standing wave

Lukáš Chvátal, Oto Brzobohatý, Pavel Zemánek

We present theoretical results related to the optical binding of two nanoparticles (NPs) in a standing wave created by a retro-reflected wide Gaussian beam. Recent experimental results demonstrated that this geometry enables easy confinement and spatial self-arrangement of NPs. Since the NPs are not usually of the same size, we investigate the influence of variations in NPs size on their stable spatial confinement in this type of optical trap.
