    Abstract

    We introduce the concept of adiabatic topological photonic structures, which allows us to overcome many of the limitations of topological photonic metasurfaces. Adiabatic variation of the mass terms at the domain walls makes topological boundary modes less sensitive to details of the lattice, perceiving the structure as an effectively homogeneous Dirac metasurface. As the result, the modes exhibit longer radiative lifetime and propagation distance, while retaining their topological resilience.
