Paper Abstract

Bessel beams are important for applications in optical trapping because they have non-diffracting and self-reconstructing properties. We fabricated a fiber device to generate a Bessel-like beam that is significantly more compact than a conventional bulk-optic Bessel beam generation system. Micro-scale dielectric particles in water are trapped and transported along the optical route formed by this Bessel-like beam. By controlling the speed and angular motion of the particles, we have demonstrated optically induced circulation of particles along triangular routes. This technique is applicable to the control of motion of living cells in a microscopic environment.
