In the push to shrink and enhance technologies that control light, MIT researchers have unveiled a new platform that pushes the limits of modern optics through nanophotonics, the manipulation of light ...

The interaction of light with solids is governed by the frequency‐dependent dielectric response, which in turn determines refractive index, absorption and reflection. In a classical continuum picture, ...

Scientists have built the first all-optical photonic time crystal, allowing them to reshape the behavior of terahertz light at extraordinary speeds. The breakthrough could open the door to ultrafast ...

A light-controlled meta-surface redirected another beam at femtosecond speeds without relying on slower electronic relaxation ...

India, July 7 -- In a significant development, researchers from Bengaluru have shown for the first time that how a metal interacts with light can be actively tuned by applying mechanical strain. The ...

Optical cavities, also known as optical resonators, are structures that confine light within a small volume by utilizing highly reflective surfaces. These cavities allow light to circulate or bounce ...

An international team of researchers from École polytechnique, Collège de France, and Helmholtz-Zentrum Dresden-Rossendorf (HZDR) has achieved a world first: the experimental realization of an ...
