Probing the chirality of a single microsphere trapped by a focused vortex beam through its orbital period
When microspheres are illuminated by tightly focused vortex beams, they can be trapped in a non-equilibrium steady state where they orbit around the optical axis. By using the Mie–Debye theory for optical tweezers, we demonstrate that the orbital period strongly depends on the particle’s chirality i...
