How shock waves travel through a superfluid provides clues to understanding the deeper nature of Bose–Einstein condensation. An optical analogue that behaves as a pure superfluid could tell us what ...

Nonlinear optics is the branch of photonics that studies material responses wherein the induced polarisation is not directly proportional to the applied electromagnetic field. In these media, intense ...

Researchers used the nonlinear optical response of atom-like defects in a diamond to build a tiny thermometer. This research may lead to temperature sensors that can work inside living cells and other ...

Structured light can significantly enhance information capacity, due to its coupling of spatial dimensions and multiple degrees of freedom. In recent years, the combination of structured light ...

A recent article in Advanced Materials reports a new fabrication method for nonlinear optical components using nanostructured polycrystalline lithium niobate (LN). The study addresses key limitations ...

Nonlinear optics has long relied on high-power lasers, whose spatial and temporal coherence ensures efficient nonlinear frequency conversion. However, a new study challenges the traditional assumption ...
