After decades of physics-based theorizing, researchers have succeeded in creating a novel optical metamaterial using conventional materials. Its enhanced electromagnetic effect may make true one-way ...

Light powers everything from communications to sensing, yet even tiny imperfections can scatter it and weaken signals. To address this, a team led by the University of Bath—working with the University ...

Photon, an elementary particle that transmits electromagnetic interaction, is a kind of gauge boson. Photons are the carriers of electromagnetic radiation, and photons are considered as the medium of ...

Plasma irradiation removes graphite from the pencil lead, exposing a thin layer of clay. By controlling the exposure time, the thickness of this layer can be varied to modulate the infrared (IR) ...

CU Boulder researchers have built high-performing optical microresonators, opening the door for new sensor technologies. At its simplest form, a microresonator is a tiny device that can trap light and ...

The study of nonlinear optical (NLO) materials has gathered substantial momentum as researchers explore their capacity to transform incident light into new frequencies. These materials underpin ...

In an era where autonomous navigation, medical diagnostics and remote sensing are rapidly evolving, traditional cameras— limited to capturing only the red, green, and blue (RGB) light intensities—are ...

For decades there has been near constant progress in reducing the size, and increasing the performance, of the circuits that power computers and smartphones. But Moore’s Law is ending as physical ...
