Optical binding in white light

Optics Letters, 2015
We experimentally demonstrate, for the first time, binding of aerosols of various sizes and shapes in white light. The optomechancial interaction between particles is long range and is in the underdamped regime. Incoherency allows mitigation of interference fringes to enable monotonically changing the distance between particles from 60 μm to contact ...

Stray Light in Optical Systems*

Journal of the Optical Society of America, 1947
An objective method has been developed for measuring the stray light in optical systems. Stray light reduces the contrast of image and falsely appears to augment the light transmission of optical system. The method utilizes a photoelectric apparatus to compare the contrast of an image formed by an optical system with the contrast of the object under ...

Light-induced optical waveguide uptapers

Optics Letters, 1993
Permanent uptapers have been produced in a UV-cured epoxy by a self-induced waveguide, created by exposure to cw 532-nm light. The photorefractive effect in this material produces high-quality, low-loss waveguides, which adiabatically taper to give spot sizes of as much as 50 μm diameter.

Slow Light in Optical Fibers

Frontiers in Optics 2007/Laser Science XXIII/Organic Materials and Devices for Displays and Energy Conversion, 2005
We describe our recent work on producing all-optical, tunable delays in optical waveguides, including schemes that can operate at high bandwidths suitable for telecommunications. Article not available.

Optical Methods—Quantitative Light Fluorescence

Journal of Dental Research, 2004
Considerable research during the past two decades has focused upon the development of new technologies for the detection of dental caries. Of these technologies, the method that has been most extensively studied is based upon the indirectly assessed changes in the fluorescence of enamel associated with the loss of mineral.

Controlling light with light: nonlinear optics applications in optical communications

Summaries of Papers Presented at the Lasers and Electro-Optics. CLEO '02. Technical Diges, 2003
Summary form only given. Nonlinear optics concepts, which are important for optical communications, are reviewed. Purely optical nonlinear processes including semiconductor optical amplifiers, non-resonant third-order susceptibilities in glasses, organic materials and semiconductors, as well as cascaded second-order nonlinearities are presented and ...

Light utilization in optical correlators

Applied Optics, 1982
An analysis is made of the overall light efficiency in a coherent optical correlator. The results are applied to a matched filter and an inverse filter. Kogelnik's coupled wave theory is applied to analyze the diffraction efficiency of a filter recorded on a high-efficiency phase medium such as dichromated gelatin.
