Subwavelength topological edge states in optically resonant dielectric structures

Slobozhanyuk, Alexey P.; Poddubny, Alexander N.; Miroshnichenko, Andrey E.; Belov, Pavel A.; Kivshar, Yuri S.


We suggest a novel type of photonic topological edge states in zigzag arrays of dielectric nanoparticles based on optically induced magnetic Mie resonances. We verify our general concept by the proof-ofprinciple microwave experiments with dielectric spherical particles, and demonstrate, experimentally, the ability to control the subwavelength topologically protected electromagnetic edge modes by changing the polarization of the incident wave.
