Researchers have developed a way to create photonic time crystals, and they have shown that these bizarre, artificial materials amplify the light that shines on them. These findings, described in a paper in Science Advances, ...
As fundamental properties of light, spectra and polarization carry vital information concerning the propagation of light waves. For example, spectral imaging can reflect the material composition of objects, while polarized ...
Holography, invented by Gabor, provides an approach for recording and reconstructing the complete information (i.e. intensity and phase) of the light from an object. Since its invention, holographic-related technologies have ...
Benefiting from superior capability in manipulating wavefront of electromagnetic waves, metasurfaces have provided a flexible platform for designing ultracompact and high-performance devices with unusual functionalities. ...
Metasurfaces, as two-dimensional metamaterials, display fascinating ability in electromagnetic (EM) modulation within a sub-wavelength scale, opening up a new way for manipulating the properties of EM wave in a plane. Owing ...
In a major breakthrough in the fields of nanophotonics and ultrafast optics, a Sandia National Laboratories research team has demonstrated the ability to dynamically steer light pulses from conventional, so-called incoherent ...
The Fourth Industrial Revolution is driving exponential growth in data transmission, and cost-effective, ultrafast, and compact optical communication technologies are urgently needed to manage the exploding data transmission ...
Micron-sized "bow ties," self-assembled from nanoparticles, form a variety of different curling shapes that can be precisely controlled, a research team led by the University of Michigan has shown.
Researchers have designed and demonstrated two all-silicon terahertz metasurface devices that can be used to create four optical channels for simultaneously implementing different optical functions. This capability could ...
Metasurfaces are highly versatile for manipulating the amplitude, phase, or polarization of light. During the last decade, metasurfaces have been proposed for a vast range of applications—from imaging and holography to ...
