Researchers at Columbia Engineering have developed a new class of integrated photonic devices—"leaky-wave metasurfaces"—that can convert light initially confined in an optical waveguide to an ...

Schematic illustration of a dynamic multifunctional metasurface based on Miura-ori. The reconfigurable origami metasurface enables the display or concealment of image information for dynamic display ...

WASHINGTON — Researchers have developed a new metasurface-based device that can produce multiple distinct holographic images depending on the surrounding medium and the wavelength of light used. The ...

A new metasurface-based device can produce multiple distinct holographic images depending on the surrounding medium and the wavelength of light used. Its ability to store information that is only ...

(Nanowerk News) The expression "flawless from every angle" is commonly used to characterize a celebrity's appearance. This doesn't simply imply that they appear attractive from a specific viewpoint, ...

Directly reconstructing the physical wavefront of objects in target scene for watched naturally by human eyes, holographic display is considered as one of ultimate display technology. Spatial light ...

University of Texas at Austin engineers advance semiconductor manufacturing with 3D printing - supported by a $14.5 million grant from DARPA.

These devices are the first to demonstrate simultaneous control of all four optical degrees of freedom, namely, amplitude, phase, polarization ellipticity, and polarization orientation--a world record ...
