Nonlinear excitation can be categorized into two types: natural and artificial. The natural type arises from the intrinsic nonlinear response of the material, while the artificial type stems from the ...

The nonlinear susceptibility is a measure of a material's nonlinear response to an applied electric field. It determines the strength of the nonlinear effects and is related to the crystal's symmetry ...

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 ...

"Our nonlinear system transmits quantum information with 94% fidelity, compared to the theoretical limit of 33% on systems using linear optical components," said Kejie Fang, an Illinois professor of ...

When light passes through a material, it often behaves in unpredictable ways. This phenomenon is the subject of “nonlinear optics”, which is now integral to technological and scientific advances – ...

Scientists at Chalmers University of Technology, Gothenburg, Sweden, have for the first time succeeded in combining two major research fields in photonics by creating a nanoobject with special optical ...
