Photonic chips demonstrate significantly lower transmission loss, broader optical bandwidth, reduced time delay, and enhanced resistance to electromagnetic interference when compared to traditional electronic integrated circuits. In recent years, programmable photonic chips have been explored for a wide range of development of new-generation network communications, artificial intelligence, and intelligent connected vehicles. This course will guide students in learning about the applications and design principles of programmable photonic chips in sensing, computing, and interconnect systems, as well as understanding their modelling, design automation, device and system optimization.
