The field of nonlinear optics investigates phenomena where the optical response of a material is not directly proportional to the incident light intensity. This nonlinearity manifests in a range of ...

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 ...

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 ...

A new bidimensional semiconductor shows the highest nonlinear optical efficiency over nanometer thicknesses. This is the result of a new study recently published in Nature Photonics by Xinyi Xu, PhD ...

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 ...

Engineers often have mixed feelings about nonlinearities in their designs' signal chains. They try to minimize them in analog circuits, whereas, for some functions, such as signal conditioners, they ...

Chalcogenide glass is widely used today in a number of specialist optics applications. Recent experiments with adding silver to the glass-forming materials that make chalcogenide glass have revealed ...
