Generation of circularly polarized nonlinear signals from chiral metasurfaces with rotational symmetry under arbitrarily polarized excitation. Left and right circularly polarized light, where the ...

Using advanced metasurfaces, researchers can now twist light to uncover hidden images and detect molecular handedness, potentially revolutionizing data encryption, biosensing, and drug safety.

Researchers from the University of Oxford have for the first time discovered an approach to electrically switch organic LEDs (OLEDs) to emit either left- or right-handed circularly polarized light ...

In a surprising twist, researchers have identified crystals that are symmetrical but nevertheless absorb light as if they were chiral (Science 2025, DOI: 10.1126/science.adr5478). The discovery ...
