Realization of dual-band topological states in Su–Schrieffer–Heeger-like photonic crystal slabs
We design the bilayer mirror-symmetric (I-shaped) photonic crystal slabs supporting dual-band topological edge states simultaneously, which is confirmed by the topological phases and localized field distributions. By adjusting the coupling strengths at different positions of the I-shaped structure,...
