Observations of a pulsar, consisting of a dead star spinning 600 times a second, and feasting on a stellar companion reveal ...

An international team of astronomers has uncovered new evidence to explain how pulsing remnants of exploded stars interact ...

Radio astronomers have detected radio pulses from a source that appears to send a signal in our direction every 14 minutes, ...

Abstract: This letter presents a reconfigurable polarization converter employing a metasurface with liquid crystals (LC) to convert linearly polarized (LP) waves into either left-hand circularly ...

As we celebrate the International Year of Quantum 2025, the frontier of light-matter interaction is undergoing a revolution. These advances are poised to transform technology, from medical imaging to ...

Now, a team led by Professor Sascha Feldmann at EPFL’s Laboratory for Energy Materials has developed a high-sensitivity, ...

Birefringence - the difference in refractive index for othogonally polarized light - can manifest in the linear coupling between orthogonal modes in a given polarization basis. Inside of a resonator, ...

EPFL scientists have developed a new technique that lets researchers watch, with unprecedented sensitivity, how materials emit polarized light over time.

Optically anisotropic bidimensional crystals offer a promising path toward compact, lithography-free polarization control in integrated photonic devices. However, most materials exhibit only modest ...
