Topological manipulation for advancing nanophotonics

Abstract Topological deformations from the hosting lattice have been applied to nanophotonics for the implementation of quantized topological states. This manipulation enables topological control of light at the wavelength scale, leading to strong light confinement and the excitation of unique resonant modes. In this Perspective, we discuss recent advances in the development of next-generation photonic devices based on topological deformations and present a comprehensive overview of ongoing research in this field.
