Plasmonic Metasurfaces for High-Resolution Optical Holography
Quick fact
Plasmonic metasurfaces can create holograms with pixel sizes smaller than the wavelength of visible light, achieving resolutions far beyond what conventional holography can offer—some demonstrations show pixel sizes of just a few hundred nanometers.
Why this is interesting
You've probably seen holograms on money or credit cards—small, shimmering images. But what if we could create holograms with resolution so high they could display 3D video in real time? That's the promise of plasmonic metasurfaces.
