Multipolar Nanophotonics and Meta-Optics

摘要

Nanophotonics aims at efficient nanoscale light manipulation, with many potential applications. Achieving the desired functionalities requires flexible control over the near-and far-field properties of nanostructures. Researchers now exploit both modal and multipolar control of the linear and nonlinear optical response of nanoscale elements to enhance near-field interaction and optimize radiation directionality. In particular, using the Kerker effect, strong directional scattering of light can be realized through the interference of magnetic and electric dipole resonances excited simultaneously with comparable strengths.
