The direction in which the electromagnetic field of circularly polarized light rotates can be easily reversed by applying a ...

A new LED design uses a built-in nanoscale metasurface to emit circularly polarized light directly, eliminating bulky optics ...

From 3D movie screens to augmented-reality devices, many modern technologies rely on our ability to manipulate light. Doing ...

Scientists at Harvard have built a miniature device that can twist and tune light in real time. By rotating two stacked ...

LAES measurement using circularly polarized light. A femtosecond laser pulse and an electron pulse were fired at an argon gas beam at the same time, giving a scattering signal whose energy and angular ...

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 ...

Researchers from the Institute for Molecular Science and Seoul National University have found that the visible luminescence from chiral gold nanoparticles, when exposed to near-infrared femtosecond ...

Tsukuba, Japan—Some beetles, such as Anomala albopilosa, strongly reflect left circularly polarized light (electromagnetic waves that oscillate leftward relative to the direction of light reception).

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

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" ...
