Multi-channel perfect absorber based on a one-dimensional topological photonic crystal heterostructure with graphene

The topological edge mode, which exists at the interface of a one-dimensional (1D) topological photonic crystal (PhC) heterostructure, provides the possibility to realize perfect absorption for its strong field localization effects. In this Letter, it is found that a huge absorption enhancement appe...
