Paper Abstract

INVITED We suggest several all-dielectric photonic structures for realising topological edge states including zigzag arrays of dielectric nanoparticles based on optically induced magnetic Mie resonances and all-dielectric metacrystals. We demonstrate experimentally the ability to control the subwavelength topologically protected optical edge modes by changing the polarization of the incident wave. In addition, we suggest theoretically and demonstrate experimentally that the photonic spin Hall effect can be enhanced by topologically protected edge states. Finally, we demonstrate that symmetry protected three-dimensional topological states can be engineered in an all-dielectric platform with the electromagnetic duality between electric and magnetic fields ensured by the structure design.
