Optical fibres made of topological photonic crystals allow improved versatility and control across the modes and polarization of light they transmit. Compositionally, photonic crystals contain bandgaps to prevent the passage ...
(Phys.org)—Researchers have designed a new type of mirror that reflects light in a completely different way than conventional mirrors do. The new mirror, called a chiral meta-mirror, has potential applications for information ...
(PhysOrg.com) -- Most of the invisibility cloaks that have been demonstrated to date conceal objects at frequencies that are not detectable by the human eye. Designing invisibility cloaks that can conceal objects from visible ...
In 2019, astronomers observed the nearest example to date of a star that was shredded, or "spaghettified," after approaching too close to a massive black hole.

Raman scattering spectroscopy is a necessary and accurate method to characterize lattice structure and probe electron-photon and electron-phonon interactions. In the quantum realm, electrons at the ground states can be excited ...
A team of researchers affiliated with multiple institutions in China, Germany and the US has found that data from the Event Horizon Telescope (EHT) rules out the likelihood of axion particles in a specific mass range around ...
Most of us control light all the time without even thinking about it, usually in mundane ways: we don a pair of sunglasses and put on sunscreen, and close—or open—our window blinds.
