Researchers found silica can outperform high-index materials for optical metasurfaces. Its chip-making compatibility enables ...

The ability to precisely control the various properties of laser light is critical to much of the technology that we use today, from commercial virtual reality (VR) headsets to microscopic imaging for ...

Metasurfaces and their novel or counterintuitive optical properties can achieve a variety of functions that conventional bulk optics components cannot. The Harvard SEAS lab of metamaterials pioneer ...

Polarization, the direction in which light vibrates, provides a lot of information about the objects with which it interacts, from aerosols in the atmosphere to the magnetic field of stars. However, ...

Metasurfaces are two-dimensional (2D), nanoengineered surfaces that interact strongly with electromagnetic waves and can control light with remarkable precision. These ultra-thin layers can be used to ...

Researcher have created a bilayer metasurface made of two stacked layers of titanium dioxide nanostructures, opening new possibilities for structuring light. (Nanowerk News) Almost a decade ago, ...

Researchers have developed a single metasurface that can effectively tune the different properties of laser light, including wavelength, without the need of additional optical components. The ...
