All-dielectric photonic topological metamaterials and metasurfaces (Conference Presentation)

Paper Abstract

The past few years have witnessed the discovery of photonic topological insulators, which transformed our views on propagation and scattering of electromagnetic waves. Here we show that judiciously designed all-dielectric photonic metamaterials and metasurfaces can exhibit a topological photonic state. The bianisotropy of the metamaterial is shown to result in emergence of a topological photonic band gap in the bulk and photonic states guided by edges and interfaces which appear to be one-way spin-polarized and immune to sharp bending. Experimental realizations of photonic topological metamaterials and metasurfaces for microwave and optical domains are used to test and confirm the topological properties.
