Engineers created a MEMS-tunable twisted bilayer photonic crystal chip that dynamically adjusts twist angle and spacing to ...

Physicists have detected laser-assisted electron scattering using circularly polarized light for the first time, revealing new ways to probe atomic-scale chirality.

In recent years, van der Waals crystals have evolved from scientific curiosities into a versatile platform for exploring novel quantum phases and unconventional nanophotonic phenomena. Their layered ...

Light is an unusually rich carrier of information. Its direction of travel, wavelength, and polarization can all be used to ...

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

A device produces green light while a researcher in lab gear stands in the background. This OLED device, which is held by a mechanical support, is producing circularly polarized light. Credit: ...

Fast radio bursts (FRBs) are a kind of energetic cosmic radio burst. Though their duration is usually at millisecond scale, their energy (estimated isotropically) reaches 10 ^36 ～10 ^41 erg, ...

Many materials emit light in ways that encode information in its polarization. According to researchers at École Polytechnique Fédérale de Lausanne (EPFL), Switzerland, polarization is key for future ...
