    Topological photonics provides new ideas for optical information processing. Furthermore, research on the application of topological edge states to construct nanophotonic devices is developing rapidly. Additionally, topological waveguides have many unique advantages in designing on-chip integrated optoelectronic devices, such as high phase-shifting efficiency and many tunable degrees of freedom, which further inspire researchers to examine and explore them extensively. The research progress based on integrated topological photonic devices is introduced. First, several typical topological lasers based on different topological systems are summarized. Second, on-chip topological passive devices, such as topological power dividers, wavelength multiplexers and demultiplexers, topological rainbows and topological filters are introduced. Third, topological integrated active devices, including topology optical switches and topology modulators, which are important devices for optical signal processing, acquisition, and conversion, are highlighted. Finally, there are topologically integrated quantum optical devices that cover topological quantum light sources and devices in topological quantum information processing. However, certain challenges remain in the application of topological photonics in integrated optoelectronic devices, such as the high loss of topological waveguides and material compatibility, which are briefly discussed in this study. The research progress on on-chip integrated topological photonic devices is summarized and future directions are explored, providing new ideas for the development of integrated optoelectronic devices.
