Optical vortex trapping of particles

Optics Letters, 1996
We demonstrate three-dimensional trapping of low-index particles (20-microm-diameter hollow glass spheres in water) by using a single, strongly focused, stationary dark optical vortex laser beam. The holographically generated vortex, which is similar to a TEM(01)* mode beam, was also used to trap and form ring patterns of high-index particles.

Optical trapping and binding

Reports on Progress in Physics, 2013
The phenomenon of light's momentum was first observed in the laboratory at the beginning of the twentieth century, and its potential for manipulating microscopic particles was demonstrated by Ashkin some 70 years later. Since that initial demonstration, and the seminal 1986 paper where a single-beam gradient-force trap was realized, optical trapping ...
