Subwavelength metal grating metamaterial for polarization-selective optical antireflection coating
A metamaterial structure consisting of a one-dimensional metal/air-gap subwavelength grating is investigated for optical antireflection for a germanium surface in the infrared regime. For incident light polarized perpendicularly to the metal grating lines, the metamaterial exhibits effective dielectric properties, and the Fabry–Perot-like resonance results in the elimination of the reflection a...
متن کاملColloidal subwavelength nanostructures for antireflection optical coatings.
A two-dimensional (2D) subwavelength nanostructure for antireflection coating is fabricated upon a transparent substrate. Self-assembled 2D colloidal crystals are used as a nanoscale composite material with controlled thickness and low refractive index. The feature size of the structure is approximately 105 nm. The structure is used for antireflection coating, and the measured reflectivity of a...
متن کاملBroadband omnidirectional antireflection coating based on subwavelength surface Mie resonators
Reflection is a natural phenomenon that occurs when light passes the interface between materials with different refractive index. In many applications, such as solar cells or photodetectors, reflection is an unwanted loss process. Many ways to reduce reflection from a substrate have been investigated so far, including dielectric interference coatings, surface texturing, adiabatic index matching...
متن کاملSubwavelength-structured polarization-selective surfaces
Subwavelength-period gratings exhibit a number of interesting polarization-selective properties. We investigate several such phenomena: an "inverse" wire-grid polarizer, which transmits TE light while stopping TM light, a guided-mode resonance filter with an order-of-magnitude difference in the width of the reflectance peak for the two orthogonal states of polarization, a metal-coated silicon g...
متن کاملThe hybrid concept for realization of an ultra-thin plasmonic metamaterial antireflection coating and plasmonic rainbow.
We report on the design, simulation, fabrication, and characterization of a novel two layer anti-reflective coating (ARC) based on a plasmonic metamaterial and a dielectric. Promoted by the strong material dispersion of the plasmonic metamaterial, our novel concept (called hybrid ARC) combines two possible arrangements for layers in an anti-reflection coating into a single structure; albeit at ...
