Topological insulator properties of photonic kagome helical waveguide arrays
We investigate topological insulator properties of the kagome helical waveguide array, by utilizing theoretical and numerical means. The time-reversal symmetry of the kagome lattice is broken by helicity, and a photonic topological insulator is formed. The Berry curvature and Chern number of the ban...
