Light is an unusually rich carrier of information. Its direction of travel, wavelength, and polarization can all be used to encode signals or images ...

Researchers have designed a metasurface that can be continuously tuned from linear to elliptical birefringence, opening up the entire space of polarization control with just one device. This single ...

image: a, Schematic of the proposed all-in-one polarizer that can function at an arbitrary position on the Poincaré sphere by design based on a dielectric metasurface composed of dimerized nanopillars ...

Mid-wavelength infrared (MWIR) as one of the most important transparent atmosphere windows is less sensitive to the interference from the background emission of the sun, providing a high-transmission ...
