摘　　要：On-chip topological nanophotonic devices,which take photons as in-formation carriers with topological protection during light propaga-tion,have great application potential in the next generation photonic chips.The topological photonic states enable the nanophotonic de-vices to be robust and stable,immune to scattering even with imper-fect structures.The development,opportunities and challenges of the on-chip topological nanophotonic devices have attracted great atten-tion of scholars,and desired to be known.In this review,topologi-cal devices were introduced in the order of functionalities on an in-tegrated photonic chip,i.e.topological light source,topological light waveguiding,topological light division and selection,topological light manipulation and topological light detecting.Finally,we gave out-looks for predicting and promoting the performances of on-chip topo-logical nanophotonic devices from the angles of non-Hermitian sys-tems,non-Abelian topology,metasurfaces,intelligent algorithms and multiple functional topological nanophotonic integration.This review provides rich knowledge about on-chip topological nanophotonic de-vices.The insights in this paper will spark inspiration and inspire new thinking for the realization of topological photonic chips.
