Flat photonics: under the electron microscope
SEM micrographs of the achromatic metasurface. An aperiodic array of dielectric resonators is patterned onto a glass substrate. The widths of the subwavelength-spaced resonators range from 100 to 800nm and each is 400nm high. Credit: Federico Capasso and Francesco Aieta, Harvard SEAS.
