Ultrathin plasmonic metasurface holograms made of subwavelength nanoslits for reconstructing both two- and three-dimensional full-color holographic images

Researchers at Missouri University of Science and Technology are creating a new approach to reconstruct 3D full-color holographic images by using just one layer of nanoscale metallic eg Aluminium film. This work has a huge potential to change our daily lives by equipping our cell phones with 3D floating displays and printing 3D security marking onto credit cards.

The researchers’ metasurface hologram is one 35-nm thick aluminum film punctured with tiny rectangular holes of 160 nm by 80 nanometers with different orientation angles created by a microfabrication process known as focused ion beam milling.

Experimenting with the interplay of ...
