Schematic illustration of photon scattering from a two-level emitter in a photonic crystal waveguide (PhC WG). A weak coherent state is coupled to the PhC WG via a shallowly etched grating (SEG). In the photon scattering image, a single-photon wave packet is mainly reflected by elastic scattering on a two-level emitter, while the two-photon wave … Read more
Multiple photonic orbitals emerge within a photonic crystal superlattice. Credit: Physical assessment B (2024). DOI: 10.1103/PhysRevB.109.235141 Researchers from the University of Twente in the Netherlands have gained important insights into photons, the elementary particles that make up light. They ‘behave’ in an astonishingly greater variety than electrons that surround atoms, while also being much easier … Read more
Illustration of the diffraction problems with particle-photon beams, and how a “self-guided” combined beam continues to provide pushing force even to distant probes. Credit: Limbach & Hara Getting to Proxima Centauri b will require a lot of new technologies, but there are increasingly exciting reasons to do so. Both public and private efforts have been … Read more
The experiment was depicted by drawing a Sagnac interferometric fiber scheme in a magnifying inset, starting from a local position (Vienna, Austria) of the rotating Earth. Two indistinguishable photons impinge on a beam splitter cube, entanglement occurs between them and then they are coupled in the fiber interferometer. Credit: Marco Di Vita A team of … Read more

Artist’s rendering of a photonic Bose-Einstein condensate (yellow) in a bath of dye molecules (red) disturbed by an external light source (white flash). Credit: A. Erglis/Albert-Ludwigs University of Freiburg Researchers from the University of Bonn have shown that superphotons, or photon Bose-Einstein condensates satisfy fundamental physics theorems and enable insights into properties that are often … Read more
Recent research has shown that a photon’s polarization is a topological property that remains constant across environments, an insight that could advance fusion research by improving the design of light beams used in plasma heating. Credit: SciTechDaily New studies show photon polarization is constant across environments and may be improving plasma heating methods for the … Read more
