Beating spectral bandwidth limits for large aperture broadband nano-optics - Nature Communications
Large aperture, diffractive metaoptics for broadband imaging have posed an outstanding challenge for miniaturized optics. In this work, Fröch, Chakravarthula, and colleagues address these challenges and successfully demonstrate a meta-optic with a 1 cm, f/2 aperture for full color imaging.
