Lateral motion of a spherical Mie particle driven by counter-propagating elliptically polarized Gaussian beams

Year: 2026

Type: article

Abstract: We numerically consider the lateral motion of levitated spherical Mie particles subject to the optical radiative forces induced by counter-propagating monochromatic Gaussian beams of elliptical polarization. In the spectral vicinity of the first magnetic and the first electric Mie resonances, the equilibrium point on the beam axis becomes unstable, and the particle transitions into a mode of lateral motion. It is found that, depending on the ellipticity of the beams, the lateral motion terminates at either one of the two off-axial fixed-point attractors or at a limit-cycle attractor. This effect paves the way for polarization control of the dynamics of particles captured by optical tweezers.
