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 ...

Metasurface holograms (meta-holograms) are ultra-thin artificial surfaces designed to shape incident light and project it to extremely wide angles. Meta-holograms have opened up numerous possibilities ...

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 ...

Brain wave synchronization, also called neuronal coherence, is a fundamental mechanism of communication in the brain, where synchronized field potentials coordinate synaptic and spiking events to ...
