Antireflection Spatiotemporal Metamaterials

Laser & Photonics Reviews, 2023
AbstractReflection occurs when light impinges on an interface between two distinct media. Suppression of the reflection is of paramount significance to practical applications in information transfer and conversion. While technologies such as the Brewster effect and material coatings are widely adopted to eliminate the wave reflection from purely ...

Biomimetic Antireflective Hierarchical Arrays

Langmuir, 2011
We 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, 2013
We 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.

Towards “perfect” antireflection coatings

Optical Interference Coatings, 2001
A 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.

Porous fluoride antireflective coatings

Applied Optics, 1988
Quarterwave antireflective coatings of CaF(2) and MgF(2) have been prepared on fused silica and calcium fluoride substrates from colloidal suspensions of the relevant fluorides in methanol. These coatings have high optical efficiency and laser damage thresholds at 350 nm in the 6-8-J/cm(2) range for single shots of 0.6-ns pulse length and 20-25 J/cm(2)

The antireflective potential of dropwise condensation

Journal of the Optical Society of America A, 2014
The transmissivity of fogged glass to visible light incident on the dry side is studied with ray tracing to show that condensation can act as an optically thick antireflective coating. A new simulation method is described that uses symmetry relations and analytical expressions for the intersection of rays and surfaces to include all drop-drop and drop ...
