New possibilities have recently emerged for producing optical beams with complex and intricate structures, and for the non-contact optical manipulation of matter. Structured Light and Its Applications fully describes the electromagnetic theory, optical properties, methods and applications associated with this new technology.

Detailed discussions are given of unique beam characteristics, such as optical vortices Author: David L.

Andrews. The applications of optical forces on matter generally engage light fields with boundaries and gradients: through the exchange of linear or angular momentum between light and matter, optical force fields and torques can be produced with no conventional counterpart.

AB - Instead of the well-known line type of phase singularities in optical and coherence fields, we introduce a new concept of what we call Vortex Sheet into singular optics.

This vortex sheet has a surface topological structure, on which the phase of the scalar optical or the coherence fields becomes undefined with zero amplitude. An important example of a chiroptical effect is the differential scattering of circularly-polarized light by chiral molecules in Rayleigh and Raman optical activity.

Here, novel forms of Rayleigh and Raman optical activity that are dependent on the sign of ℓ and thus the orbital angular momentum of light.

On the propagation of radiation with a suitably resonant optical frequency through a dense chromophoric system - a doped solid for example - photon capture is commonly followed by one or more near-field transfers of the resulting optical excitation, usually to closely neighboring chromophores.

At the same time, effects like ‘optical pulling force’ [3, 4], ‘stable optical lift’ [5], and optical micromotors [6, 7] emphasize the role of the object shape for exploiting mechanical effects from optical momentum.

MIT Department of Physics. (Dated: August 11, ) An optical trap or \optical tweezers" is a device which can apply and measure piconewton sized forces on micron sized dielectric objects under a microscope using a highly focused light beam.

We propose a quantum theory of rotating light beams and study some of its properties. Such beams are polychromatic and have either a slowly rotating polarization or a slowly rotating transverse mode pattern. We show there are, for both cases, three different natural types of modes that qualify as rotating, one of which is a new type not previously considered.

We discuss differences between. Search the leading research in optics and photonics applied research from SPIE journals, conference proceedings and presentations, and eBooks. We use an algebraic method to derive explicit expressions for the structure of paraxial modes in a cavity consisting of astigmatic mirrors.

The algebra is based upon the use of ladder operators that raise or lower the mode indices, when acting on a mode function. We show that the method is also applicable when the mirrors perform a uniform rotation about their axes.

We also find expressions. The nanowires in aqueous solution are attracted toward the waveguide by optical gradient forces. The nanowires align themselves according to the axis of the waveguide and get propelled along the waveguide due to radiation pressure.

Optical tweezers, however, owe their trapping to the gradient jorce, which is instead proportional to the spatial gradient in light intensity and acts in the direction of that gradient. Other optical forces include, for example, the optical binding jorce, which is an interaction between particles in intense light (30, 31).Advance Technical Program Conferences + Courses: 19–24 January Biomedical Optics Exhibition: January Photonics West Exhibition: 22–24 January Optical forces and torques in non-uniform beams of light David B.
