Abstract
In recent years, 5G photonic technology has gradually gained increased attention from scholars. However, studies on 5G photonic technology have mostly focused on technological discussions or market development research, but have failed to identify the relevant key technologies from a comprehensive perspective. In particular, 5G photonic technology is an interdisciplinary technology that could create considerable potential business opportunities in the future, therefore, identifying related key technologies is crucial. Accordingly, the patents of 5G photonic technologies were used as the basis for analysis in this study, and a patent technology network for such technologies was constructed using network analysis. The results showed that the key technologies of 5G photonic technology are mainly related to optics, nanostructures, semiconductors, and material analysis, indicating an interdisciplinary feature instead of focusing only on one specific technological field. Additionally, the relevant technologies that have seen active development in recent years are mainly related to optical elements and semiconductor devices. Finally, a patentee analysis demonstrated that information technology companies were the key players in the development of 5G photonic technologies, and the semiconductor industry will have a crucial role in the development of such technologies. In this study, a patent technology network model was constructed to explore the development trend of 5G photonic technologies, thereby providing a reference for the government to promote these emerging technologies.
Highlights
Photonics is a science that explores the use of photons as information and energy carriers [1].Photons are characterized by a lack of electric charge and mass, low energy consumption, and insusceptibility to external influences
Internet of Things (IoT), automated vehicles, and smart homes) and photonic technology is the key technology for the implementation of 5G, this study focused on 5G photonic technology and explored the relevant key technologies and their development trends
In terms of the development potential of 5G photonic technology, this study mainly focused on photonic technology in 5G and determined its key technologies through patent analysis
Summary
Photonics is a science that explores the use of photons as information and energy carriers [1]. 5G is a key technology in many growth sectors that provide key services, such as autonomous vehicles, smart factories, and smart healthcare [11,12,13] These service applications, which were previously constrained in speed and stability under 4G networks, could be implemented following the advent of 5G. A comprehensive examination was conducted of the layout of 5G technologies and an overall picture of photonic technology in 5G was presented from a macro perspective, focusing on the establishment of a technology network model and the analysis of technology development trends. This can provide a valuable reference for the government, researchers, and industry professionals
