Optical fibres made of topological photonic crystals allow improved versatility and control across the modes and polarization of light they transmit. Compositionally, photonic crystals contain bandgaps to prevent the passage ...
The Cambridge Research Laboratory of Toshiba Europe today announced the first demonstration of quantum communication over optical fibers exceeding 600 km in length. The breakthrough will enable long-distance, quantum-secured ...
