Topological rainbow trapping based on gradual valley photonic crystals
Valley photonic crystals (PCs) play a crucial role in controlling light flow and realizing robust nanophotonic devices. In this study, rotated gradient valley PCs are proposed to realize topological rainbow trapping. A topological rainbow is observed despite the presence of pillars of different shap...
