Researchers in the US have demonstrated how quantum entanglement could be used to detect optical signals from astronomical ...

Researchers at the Leibniz Institute of Photonic Technology (Leibniz IPHT) in Jena, Germany, together with international collaborators, have developed two complementary methods that could make quantum ...

Conventional optics (e.g. lenses or mirrors) manipulate the phase via optical path difference by controlling thickness or refractive index of material. Recently, researchers reported that arbitrary ...

A career in optical physics or engineering means knowing about the behavior and properties of light, including its interactions with matter and its detection by instruments. Since the discovery that ...

Mini-MOT: A new miniaturized optical system for laser cooling atoms in a magneto-optical trap, or MOT. (Courtesy: NIST) The magneto-optical trap, or MOT, is the workhorse of cold-atom physics. Without ...

Nvidia invested $4 billion in Lumentum, Coherent, and Ayar Labs to secure optical interconnect supply. The deals build competitive moats as AI clusters hit power limits.
