Abstract
A meta-optical device, which imparts a phase delay to incident light of a wavelength band, includes: a first electrode and a second electrode spaced apart from each other; a liquid crystal layer between the first electrode and the second electrode; a meta-surface layer located within the liquid crystal layer and including a plurality of nanostructures each having a shape dimension smaller than a center wavelength of the wavelength band; and a voltage device configured to apply a voltage between the first electrode and the second electrode. The meta-optical device may exhibit an electrically controlled variable focal length.
