Optical vortex manipulation

Frontiers in Optics, 2003
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 Cell Manipulation

2010
In current biotechnology and biomedicine, cell-based investigations are rapidly gaining importance due to the recognition that molecular research alone does not provide a sufficiently complex insight. The high cost of animal studies and the fact that their results often cannot be directly transferred to humans additionally shifts the focus towards cell-

Optically manipulating superconductors

Science, 2014
Superconductivity 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 ...

Micro-Optical Elements for Optical Manipulation

Optics and Photonics News, 2006
Using 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.

Plasmon-based optical manipulation

2007 European Conference on Lasers and Electro-Optics and the International Quantum Electronics Conference, 2007
The current work provides a first experimental demonstration of a novel in-plane manipulation method based on the action of SP forces rather than conventional photonic forces, both at homogeneous and patterned metal surfaces.

A revolution in optical manipulation

Nature, 2003
Optical tweezers use the forces exerted by a strongly focused beam of light to trap and move objects ranging in size from tens of nanometres to tens of micrometres. Since their introduction in 1986, the optical tweezer has become an important tool for research in the fields of biology, physical chemistry and soft condensed matter physics.

Optical Manipulation of Hydrosomes

Frontiers in Optics 2009/Laser Science XXV/Fall 2009 OSA Optics & Photonics Technical Digest, 2009
We present a novel implementation of optical tweezers and microfluidics that allow for the controlled production and manipulation of monodisperse water droplets in an immiscible phase - hydrosomes.

Optical Manipulation of Microscale Fluid Flow

Physical Review Letters, 2003
A novel optical method is used both to probe and to control dynamics in experiments on the spreading of microscale liquid films over solid substrates. The flow is manipulated by thermally induced surface-tension gradients that are regulated by controlling the absorption of light in the substrate.

GPC-based optical manipulation

Adaptive Optics: Analysis and Methods/Computational Optical Sensing and Imaging/Information Photonics/Signal Recovery and Synthesis Topical Meetings on CD-ROM, 2005
The Generalized Phase Contrast (GPC) method enables conversion of phase-only modulation to highly photon efficient light distributions. GPC targets a number of applications such as interactive optical manipulation, wavefront sensing, optical encryption and integrated micro-optics.

Optical manipulation for single‐cell studies

Journal of Biophotonics, 2010
AbstractIn the last decade optical manipulation has evolved from a field of interest for physicists to a versatile tool widely used within life sciences. This has been made possible in particular due to the development of a large variety of imaging techniques that allow detailed information to be gained from investigations of single cells.
