Advanced Materials, 2011
Based on conventional colloidal nanosphere lithography, we experimentally demonstrate novel graded-index nanostructures for broadband optical antireflection enhancement including the near-ultraviolet (NUV) region by integrating residual polystyrene antireflective (AR) nanoislands coating arrays with silicon nano-conical-frustum arrays.

Biomimetic Antireflective Hierarchical Arrays
Langmuir, 2011We report a simple method for the fabrication of biomimetic antireflective hierarchical arrays based on the combination of self-assembled polymer spheres and nanoimprint lithography (NIL). The hierarchical structures are fabricated by creating nanopillars on the microscale round protrusion arrays, which are similar to natural mosquito eyes consisting ...

Optimal broadband antireflective taper
Optics Letters, 2013We have solved the optimal taper design for minimizing reflection over a broad frequency band for a given tapered length. We believe this work will lead to significant improvement in developing broadband antireflective devices in many areas.

Antireflective MoSi photomasks
Journal of Vacuum Science & Technology B: Microelectronics and Nanometer Structures Processing, Measurement, and Phenomena, 1992Antireflective MoSi (AR-MoSi) photomasks which are produced by applying a thin layer of MoSi oxide directly over the conventional MoSi layer on a quartz substrate has been developed. The thin layer of MoSi oxide is deposited using magnetron dc sputtering. The reflectivity and optical density of the thin layer are not affected by H2SO4 at 120 °C.

Towards “perfect” antireflection coatings
Optical Interference Coatings, 2001A perfect antireflection coating would remove the reflection from the interface between two media for all wavelengths and angles of incidence. In this paper the degree to which this can be achieved is investigated numerically, theoretically and experimentally.

Broadband antireflective random metasurfaces
Journal of the Optical Society of America B, 2021In this work, we propose and numerically investigate broadband antireflective random metasurfaces. We demonstrate that a random monolayer of identical metallic subwavelength spherical particles, deposited on a substrate, is able to suppress the reflection in a broadband spectral region over a wide range of incident angles and that it is insensitive to ...
