Our research has been spotlighted on the cover of Nano Letters, Volume 26, Issue 12 , dated April 1, 2026. About the Cover: A topology-optimized nonlocal metasurface enables high-Q RGB resonances for compact augmented reality combiners. With the engineering of two-dimensional guided-mode interactions, the freeform structure selectively diffracts display light while transmitting ambient light, achieving vivid color purity and reduced spectral leakage. This work advances multi

What if AR glasses could become lighter, clearer, and more energy-efficient—without sacrificing color quality? Our research team at National Yang Ming Chiao Tung University has taken an important step toward that vision. In a recent publication in Nano Letters , we report a two-dimensional topology-optimized nonlocal metasurface that enables highly selective control of red, green, and blue light within a single ultrathin layer. Unlike conventional metasurfaces that struggle t
