In a new study published in Nature Physics, researchers have demonstrated the Hong–Ou–Mandel (HOM) effect with up to 12 ...

With the super-election year of 2024 in the rearview mirror, there is a lot to learn from the elections that have taken place in Europe during a period of increasing geopolitical tensions. In ...

Diffraction refers to the bending of waves, such as light, when they encounter obstacles or pass through small openings. The size of the opening relative to the wavelength of light influences the ...

No one can question the impact of science on human civilization, and the importance of experimentation in science is equally undeniable. Some experiments confirm what we already know, others suggest a ...

The generation of phase-stable femtosecond X-ray pulse pairs will advance nonlinear spectroscopies and imaging, providing direct insight into the coupled motions of electrons and nuclei with ...

The present paper examines the viability of a radically novel idea for brain–computer interface (BCI), which could lead to novel technological, experimental, and clinical applications. BCIs are ...

The light propagation in the medium normally experiences diffraction, dispersion, and scattering. Studying the light propagation is a century-old problem as the photons may attenuate and wander. We ...

Abstract: Structured light, which exhibits nontrivial intensity, phase, and polarization patterns in space, has key applications ranging from imaging and 3D micromanipulation to classical and quantum ...

Thomas Young’s double-slit experiment is famous for demonstrating the principle of interference. Andrew Murray explains why it’s now possible to carry out an equivalent experiment using lasers that ...

Electro-optical detectors are used to measure or sense the radiation emitted or reflected by objects within the detector’s optical field of view (FOV). Passive systems operate without any illumination ...
