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 ...

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 ...

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 ...
