Table 1 Hydrodynamic velocities of single 3 μm polystyrene beads. Speed of particles is calculated using different correction factors for the LP01 and LP11 microfibre modes. The power at the fibre waist regions Pwaist was fixed at 25 mW
From: Higher order microfibre modes for dielectric particle trapping and propulsion
