Topologically distinct photonic crystals

Caption

Topologically distinct photonic crystals (orange and blue) with a layer of hexagonal boron nitride on top enable coupling of topological light and lattice vibrations to form chiral half-light half-vibration excitations, which can be directionally guided along 1D channels in robust manner.
