Polarized light is one of the most powerful tools scientists have for peering inside matter, yet the way it twists, scatters ...

Photoplethysmography (PPG) is an optical sensing technique that measures blood volume changes and underpins devices ranging ...

Forget LEDs, researchers from the University of Michigan have developed a new type of incandescent light bulb. The device is capable of emitting elliptically polarized light, described as "twisted" ...

A new mechanism steers diodes made of a single enantiomer to emit light of right- and left-handed polarizations ...

New method identifies altermagnets by signatures from circularly polarized light, validated in MnTe, speeding discovery for ...

Scientists at the University of Oxford demonstrate an approach to interpreting how materials interact with polarized light, ...

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

The photo showed the first image in polarized light of the supermassive black hole at the center of the Milky Way galaxy. However, it was not the first-ever image of the astronomical object. That was ...

Researchers at Brown University have developed a wearable sensor that uses polarized light to improve the accuracy of ...
