The fine and efficient control of the properties of light at ultrafast speed down to the picosecond timescale is a challenging task, crucial for many scientific applications and technologies. For instance, in free-space optical ...
An article in Opto-Electronic Advances, discusses complete-basis-reprogrammable coding metasurface for generating dynamically-controlled holograms under arbitrary polarization states.
Optical metasurfaces are finely crafted two-dimensional artificial nanostructures composed of meticulously designed arrays of ultrathin artificial atoms. These surfaces possess capabilities beyond natural materials, enabling ...
Researchers with the Advanced Science Research Center at the CUNY Graduate Center (CUNY ASRC) have experimentally demonstrated that metasurfaces (two-dimensional materials structured at the nanoscale) can precisely control ...
Metasurfaces are two-dimensional counterparts of metamaterials, which are artificial materials that possess unusual characteristics. With a variety of fascinatingly innovative and diverse uses, these specially-prepared surfaces ...
Augmented reality (AR) has evolved from a futuristic concept to a widespread technology, thanks to advancements in microdisplay technologies, ultracompact imaging optics, and high-speed digital processors.
Scientists from the Department of Â鶹ÒùÔºical Chemistry at the Fritz Haber Institute of the Max Planck Society have made a significant discovery in the field of nanotechnology, as detailed in their latest publication in Advanced ...
Metalens is a kind of optical metasurface composed of metaatoms for manipulating incoming light's amplitude, phase, and polarization. Unlike traditional refractive lenses, metalens can modulate the wavefront from plane to ...
Computer-generated holography (CGH) provides an approach to digitally modulate a given wavefront. This technology, partly inherited from optical holography and partly advanced by the progress of computing technology, has ...
It is a scene many of us are familiar with: You're working on your laptop at the local coffee shop with maybe a half dozen other laptop users—each of you is trying to load websites or stream high-definition videos, and ...
