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 ...

Advancements in photonic integration demand high-speed, precise dynamic light field control and large-capacity information processing capability. As subwavelength artificial structures, metasurfaces ...

Meta-holograms, the computer-generated holograms assisted with nano-structured metasurfaces, promise efficient recording of light at the nanoscale. Adopting the multiplexing principle further bestows ...

Metasurface converts Gaussian beams to uniform light via polarization encoding, boosting NMR co-magnetometer sensitivity 23% for compact quantum sensors.

Using quantum effects in a 2D material, researchers created a tunable metasurface that toggles between reflecting and absorbing red light at room temperature. (Nanowerk News) Controlling light is an ...

Controlling light is an important technological challenge—not just at the large scale of optics in microscopes and telescopes, but also at the nanometer scale. Recently, physicists at the University ...
