Progress on quantum-inspired sensing of optically trapped microparticles — •Stefan Berg-Johansen^1,2, Martin Neugebauer^1,2, Peter Banzer^1,2, Andrea Aiello^1,2, Gerd Leuchs^1,2,3, and Christoph Marquardt^1,2 — ¹Max Planck Institute for the Science of Light, Staudstr. 2, D-91058 Erlangen, Germany — ²Institute of Optics, Information and Photonics, University of Erlangen-Nuremberg, Staudtstr. 7/B2, D-91058 Erlangen, Germany — ³Department of Physics, University of Ottawa, 25 Templeton, Ottawa, Ontario, K1N 6N5 Canada

We experimentally demonstrate optical trapping and simultaneous kinematic tracking in three dimensions of a dielectric microparticle using only a single beam. Our approach is based on the nonseparability of polarization and transverse spatial degrees of freedom in cylindrically polarized modes [1,2].
