Nanoimprint lithography for high-throughput fabrication of metasurfaces

open access: yesFrontiers of Optoelectronics, 2021
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 applications such as holograms, wavefront shaping, and structural color printing, however, electron-beam lithography is not suitable to produce large-area metasurfaces because of

Light‐Controlled Fabrication of Disordered Hyperuniform Metasurfaces

open access: yesAdvanced Materials Technologies, 2022
AbstractDisordered hyperuniformity (DHU) is one of the most prominent manifestations of the engineered disorder, which aims to circumvent limitations commonly related to order. Considering the k‐space, isotropic DHU is characterized by an isotropic suppression of scattering for wavenumbers k approaching zero.
