Researchers at NYCU have developed an ultrathin nonlocal metasurface capable of precisely controlling red, green, and blue (RGB) light using a single nanoscale layer. The breakthrough could significantly reduce the size of optical systems while improving image quality, color fidelity, and energy efficiency.
The technology could accelerate the development of lightweight augmented reality (AR) glasses, compact microdisplays, smartphone cameras, and other next-generation optical devices. The study was published online in Nano Letters on March 2, 2026. It was subsequently selected for the cover of the journal’s April 1, 2026 issue, highlighting its significance in nanophotonics and nonlocal metasurfaces.
