Over the past few years, engineers and material scientists have been trying to devise new optical systems in which light ...

Ultrathin structures that can bend, focus, or filter light, metasurfaces are reshaping how scientists think about optics.

Redefining the repeating pattern in photonic crystals creates tightly confined pathways for light while preserving symmetry, ...

Researchers at the University of Tsukuba have developed a novel method for controlling the optical rotation of conductive ...

A new liquid crystal device lets scientists control how light twists and behaves using voltage, making it possible to reshape light patterns without changing the physical structure of the device.

The material, called a colorless and unidirectional diffractive-type solar concentrator (CUSC), works by steering some of the sun’s rays to the edges of the glass, where photovoltaic strips convert th ...
