Abstract: Next-generation optical transmission networks are evolving toward ultra-high capacity, ultra-long distance, high flexibility, and low energy consumption. These advancements are driven mainly by innovations in key devices and breakthroughs in integration technologies. The characteristics and selection of optoelectronic integration platforms are systematically reviewed, and the latest research progress on key devices, including tunable light sources, integrated transceiver chips, integrated optical waveguide amplifiers (EDWAs), and intelligent optical switching devices, is thoroughly discussed and examined. Based on this analysis, the applications of these technologies in ultra-high-capacity transmission systems, data center interconnections (DCI), and 5G bearer networks are examined. Finally, the major challenges currently faced are summarized such as multi-material heterogeneous integration, thermal management, and packaging costs, and looks ahead to future trends, including co-packaged optics (CPO), wafer-level manufacturing, and intelligent optical networks.
