The invention of tiny devices capable of precisely controlling the direction and behavior of light is essential to the ...

Researchers developed a nonlinear nonlocal metasurface that converts infrared light to visible and steers it by combining ...

Researchers have built a paper-thin chip that converts infrared light into visible light and directs it precisely, all without mechanical motion. The design overcomes a long-standing efficiency-versus ...

Metasurfaces in which nonlocal light-matter interactions take place are a potentially useful variant of traditional ...

A team of researchers at Penn State have devised a new, streamlined approach to designing metasurfaces, a class of engineered materials that can manipulate light and other forms of electromagnetic ...
