Phys.org July 29, 2024 Researchers in the UK summarized recent progress in the development and applications of microstructured optical fibers for quantum technologies. The optical nonlinearity of solid-core and gas-filled hollow-core fibers provides a valuable medium for the generation of quantum resource states as well as for quantum frequency conversion between the operating wavelengths of existing quantum photonic material architectures. The low loss, low latency, and low dispersion of hollow-core fibers make these fibers particularly attractive for both short- and long-distance links in quantum networks. Hollow-core fibers also promise to replace free-space optical components in a wide range of atomic […]

The optical fiber that keeps data safe even after being twisted or bent
Science Daily January 10, 2023 Topological states enable robust transport within disorder-rich media. However, to exploit topological protection in a length-scalable platform such as optical fiber remains a challenge. Through modeling and experiment a team of researchers in the UK demonstrated that optical fiber hosts topological supermodes across multiple light-guiding cores. They directly measured the photonic winding number invariant characterizing the bulk and observed topological guidance of visible light over meter length scales. The mechanical flexibility of fiber allowed them to reversibly reconfigure the topological state. As the fiber was bent, they found that the edge states first lost their […]
