Optical metasurfaces with subwavelength thickness hold considerable promise for future
advances in fundamental optics and novel optical applications due to their unprecedented …

Metasurfaces are composed of periodic sub-wavelength nanostructures and exhibit optical
properties that are not found in nature. They have been widely investigated for optical …

Metalenses have shown a number of promising functionalities that are comparable with
conventional refractive lenses. However, current metalenses are still far from …

Printable metalenses composed of a silicon nanocomposite are developed to overcome the
manufacturing limitations of conventional metalenses. The nanocomposite is synthesized by …

We report a one-step additive manufacturing process to fabricate metalenses for visible
wavelengths. Nanostructures with aspect ratios larger than eight and critical dimensions …

Shortly after its inception, nanoimprint lithography (NIL) was primarily used as tool for the
thermal embossing and flash curing of thermoplastic resists and polymer precursors …

We review past and recent progress in nanoimprint lithography (NIL) methods to (nano-)
structure inorganic materials from sol–gel liquid formulations and colloidal suspensions onto …

Structural colors refer to colors produced by the interference of light scattered by judiciously
arranged nano-or microscopic structures. In this Forum Article, we discuss the use of Mie …

A metasurface is a layer of subwavelength-scale nanostructures that can be used to design
functional devices in ultrathin form. Various metasurface-based optical devices–coined as …

Structural color, which generates vivid colors via the geometrical arrangement of resonant
nanostructures, can enhance the recyclability and mechanical stability of colors; structural …
