Capasso Group Revolutionizes Flat Lenses

Researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences have developed a single flat lens that can focus the entire visible spectrum of light in the same spot and in high resolution. Professor Federico Capasso and members of the Capasso Group explain why this breakthrough in metalenses could have major implications in the field of optics, and could replace bulky, curved lenses currently used in optical devices.
