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

Chiral metasurfaces can strongly twist the polarization of light, but how this process unfolds in space and time has been unclear. Scientists in China have now used ultrafast electron microscopy and ...

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

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 ...
