Paper Abstract

In this paper we elucidate the peculiar behaviour of optically bounded micron-sized objects. For these studies we have modified algorithm based on the coupled dipole method (CDM), which is currently the most effective tool for the analysis. We present how to simulate the optical binding of two dielectric spheres placed in two counter-propagating non-interfering Gaussian laser beams. The results give us an insight into the background of forces acting between optically bound particles concerning the phenomenon of multi-stable particle separations.
