In recent years, van der Waals crystals have evolved from scientific curiosities into a versatile platform for exploring novel quantum phases and unconventional nanophotonic phenomena. Their layered ...

What are Tunable Optical Materials? Tunable optical materials are a class of nanomaterials that can manipulate light in a controllable and dynamic manner. These materials have optical properties, such ...

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) ...

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 ...

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 ...

The material the team studied, barium titanium sulfide (BaTiS 3), a hexagonal crystal, was already known to have large optical anisotropy, but scientists couldn't figure out why. It took years of back ...

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 ...
