"far-field interference of multipoles and the near-field properties of topological charges. Recent works on manipulating the far-field radiation properties of BICs through engineering topological charges are then highlighted... chiral light and vortex beam generation, harmonics generation, sensors, lasing, THz generation, detection, modulation, sensing, and isolation... classical optical regime and quantum photonics"
