With the development of 5G, mobile communication, and optical communication technologies, semiconductor optical amplifiers (SOAs) have become an important research topic. However, most SOA-related studies have focused on a technical discussion or market research but have failed to indicate the critical SOA technologies and the SOA technology development trends. Therefore, this study analyzes SOA patents and constructs a technology network for SOA patents. The results indicate that the critical SOA technologies are mainly used in lasers, semiconductor lasers, light guides, electromagnetic wave transmission communication other than radio-wave communication, and devices controlling light sources. Among the five critical SOA technologies, lasers (H01S3) account for the highest percentage at 22.21%. Consequently, the critical technologies do not focus on specific technology fields but have characteristics of multiple technology fields. In addition, considerable development has occurred in semiconductor lasers in recent years. Finally, patentee analysis indicates that for SOA technologies, the public sector and academia play relatively weak roles in early technology development or following technology development. However, with the rapid development of mobile communication and optical communication, the government of each country can consider investing additional R&D funds and resources in the future. This study constructs a network model for patent technologies to explore the development tendencies for SOA technologies. This model can be used as a reference for R&D resource management and the promotion of new technologies.

Subject COVID-19 and the surveillance state. Significance COVID-19 has prompted the government and private technology companies to focus resources on rapid development of new technologies. The country has rapidly developed and rolled out checkpoints, apps and programmes in response to the outbreak. Many will cease to be useful after the pandemic ends, but some will likely be retained, enhanced and turned to other purposes. Impacts Firms and the state can work well together at different levels and rapid speeds to develop technology in response to urgent needs. Chinese capabilities in areas such as facial recognition will be permanently enhanced. New types of monitoring may be used to assess citizens’ performance or entitlements in fields such as policing and ‘social management’.

Queen Effect

This chapter introduces the idea that technology, invented millennia ago, is developing at an even increasing pace, creating the need for all systems to develop to avoid becoming obsolete. This is called the Red Queen effect. The current generation has seen the appearance and rapid development of many new technologies, from digital computers and cellular phones, to DNA sequencing and genetic engineering. However, the next decades will witness an even faster technological development, leading to the appearance of economic and social realities that we cannot even dream of. Computer technology and biotechnology will come together to create changes in society that will make the last decades look like slow-paced, in what respects technology development.
