Nanophotonics and topological photonics are optical frontiers research, which involve the use of structures and devices to manipulate light. The field of nanophotonics and topological photonics have applications in various areas such as light propagation, optical information processing, data storage, energy harvesting, and imaging. This session topics include nanophotonic devices, on-chip integration, topological photonic crystals, metamaterials, exceptional points and modes in photonic systems, nonlinear photonics, with novel theoretical models, fabrication methods, new experiments, and related applications in nanophotonics and topological photonics.
