Abstract

We studied the optical forces acting on a microscopic object generated by the laser beams from lensed optical fiber ends to research the parametric influence on the optical trapping. From these investigations, we verified that there was only one stable point of equilibrium located below the beam-crossing point, and revealed that the radius of a hemispherical microlens of an optical fiber end, the horizontal distance between each optical fiber end and the particle size are important parameters for strong three-dimensional trapping without physical contact.
