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 ...

In a recent article published in the journal Light: Science & Applications, researchers explored a fundamental but often overlooked area of optical science: how spatial coherence can be controlled and ...

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 ...
