A nanoscale optical device has been developed that allows independent control over the intensity and phase of light. By ...

The demonstrated QCMs can reconstruct holographic images and display diffraction patterns simultaneously. Silicon nanofins are arranged in the Penrose tiling pattern as illustrated by the 2D color ...

A U.K.-Portuguese research group is proposing a new solar cell design based on diffraction gratings – optical components that split and diffract light into several beams. They claim this could lead to ...

THE attention given, in this laboratory and elsewhere, to the effects produced by passing a beam of Röntgen radiation through crystals suggested to me that it might be of interest to examine the image ...

New twist: a smeared out signal can transform into a soliton, depending on the laser powers and the twist angle of the optical moiré lattice. (Courtesy: Fangwei Ye) Moiré lattices — wherever they form ...

Imagine a cube on which light is projected by a flashlight. The cube reflects the light in a particular way, so simply spinning the cube or moving the flashlight makes it possible to examine each ...

Definition: X-Ray Diffraction (XRD) is a powerful analytical technique used to characterize the atomic and molecular structure of a crystal. By measuring the angles and intensities of diffracted beams ...
