Optical vortices can provide mechanisms for micromanipulation of micron or sub-micron sized particles as well as a means to generate complicated array patterns. Particularly interesting is the way in which higher order vortices can be triggered by a secondary optical field to explode or implode.

Optical manipulation of particle ensembles in air
Optics Letters, 2012 We demonstrate that airborne light-absorbing particles can be photophoretically trapped and moved inside an optical lattice formed by multiple-beam interference. This technique allows simultaneous three-dimensional manipulation of multiple micro-objects in gases.

Single-cell analysis can reveal cell behaviors that are unobservable by traditional bulk measurements. The analysis of single cells is made possible by technology that enables the addressing and manipulation of microscale objects. Optical manipulators are capable of micro- and nano-manipulation and are attractive for single-cell procedures, due to ...

Micro-Optical Elements for Optical Manipulation
Optics and Photonics News, 2006Using micro-optical elements can be an effective, low-cost way to shape laser micro-beams, which are needed for optical trapping and manipulation. This article covers various designs of micro-optical elements that are used to generate the necessary optical vortices within a beam.

Optically manipulating superconductors
Science, 2014Superconductivity In superconductors, electrons of opposite momenta pair to form a highly correlated state that manages to flow without encountering any resistance. Matsunaga et al. manipulated the wavefunction of these pairs in the superconductor NbN with an electromagnetic pulse that they transmitted through a thin layer of the material (see the ...

Optical manipulation of microspheres along a subwavelength optical wire
Optics Letters, 2007The propulsion of 3 microm polystyrene spheres along a subwavelength optical wire is demonstrated. Velocities in the range of 7-15 microm/s are observed. Simulations are carried out to evaluate the evanescent field at the waveguide-water suspension interface.
