Topological photonic crystals in the visible: design and angle-resolved characterization of the bulk and edge states


We fabricated and characterized photonic crystals with non-trivial topological bulk states and pseudo-time-reversal-symmetry protected helical edge states in the visible regime. With a 30-keV electron beam, we excite coherent cathodoluminescence in the nanostructured material and derive photonic band structures.
