Check out our recent News & View article ‘Symmetry breaking in thermal photonics.’ in Light: Science and Applications. Thermal radiation is omnipresent and is engineered for various applications in modern photonics, such as cooling, imaging, and energy harvesting. Symmetries and symmetry breaking...

We discuss the engineering of the spatial and temporal properties of both the electric permittivity and the refractive index of materials is at the core of photonics. When vanishing to zero, those two variables provide efficient knobs to control light–matter interactions. This Perspective aims at...

A new approach to control forces and interactions between atoms and molecules, such as those employed by geckos to climb vertical surfaces, could bring advances in new materials for developing quantum light sources.

A newly described property related to the "spin" and momentum of light waves suggests potential practical applications in photonic communications and photonic circuits. Scientists already knew that light waves have an electric field that can rotate as they propagate, which is known as the polarization property of light, and that light waves carry momentum in their direction of motion. In new findings, researchers have discovered a "spin-momentum locking," meaning, for example, light waves that spin in a counterclockwise direction can only move forward, and vice versa.
