Tunable 'metasurface' is akin to optical swiss army knife

MIT engineers and colleagues report important new advances on a tunable metasurface, or flat optical device patterned with nanoscale structures, that they compare to a Swiss army knife while its passive predecessor can be ...

Graphene 'smart surfaces' now tunable for visible spectrum

Researchers at The University of Manchester's National Graphene Institute have created optical devices with a unique range of tunability, covering the entire electromagnetic spectrum, including visible light.

Researchers develop photostimulated transparent glass ceramic

Magnetic data storage has been gradually replaced by optical data storage (ODS) with higher efficiency, lower energy consumption, larger capacity, and longer service lifetime. As a classical kind of ODS medium, photostimulated ...

Graphene layer enables advance in super-resolution microscopy

Researchers at the University of Göttingen have developed a new method that takes advantage of the unusual properties of graphene to electromagnetically interact with fluorescing (light-emitting) molecules. This method allows ...

Dense yet transparent materials offer new way to control light

Researchers recently made the surprising discovery that a special class of materials called "hyperuniform materials" can be both dense and transparent. This work demonstrates a new way to control light and could lead to novel ...

Silicon-based metamaterials could bring photonic circuits

New transparent metamaterials under development could make possible computer chips and interconnecting circuits that use light instead of electrons to process and transmit data, representing a potential leap in performance.

Transparent metal films for smart phone, tablet and TV displays

A new material that is both highly transparent and electrically conductive could make large screen displays, smart windows and even touch screens and solar cells more affordable and efficient, according to the Penn State ...

Nanopaper as an optical sensing platform

An international team led by the ICREA Prof Arben Merkoçi has just developed new sensing platforms based on bacterial cellulose nanopaper. These novel platforms are simple, low cost and easy to produce and present outstanding ...
