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

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" ...

Photoplethysmography (PPG) is an optical sensing technique that measures blood volume changes and underpins devices ranging from hospital-grade pulse oximeters to consumer wearables that track heart ...

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

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

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 ...

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

Astronomers have captured the first view of polarized light and the magnetic fields that surround Sagittarius A* (Sgr A*), the supermassive black hole at the heart of the Milly Way. The new EHT ...
