Plasmonic metamaterials exhibit strong and tunable dispersion , as a result of their pronounced resonances. This dispersion is used to construct an ultrathin light‐shaping element that produces different waves at two distinct wavelengths in the near IR range. The optical response of the pixelated element is adjusted by variations in the geometry of the metamaterial's unit cell. Applications requiring spatial and spectral control of light become feasible.
