In the last decade, silicon photonic switches are increasingly believed to be potential candidates for replacing the electrical switches in the applications of telecommunication networks, data center and high-throughput computing, due to their low power consumption (Picojoules per. In the last decade, silicon photonic switches are increasingly believed to be potential candidates for replacing the electrical switches in the applications of telecommunication networks, data center and high-throughput computing, due to their low power consumption (Picojoules per. NVIDIA's co-packaged optics (CPO) switches with integrated silicon photonics are the world's most advanced networking solution for the era of agentic AI. This review focuses on recent developments and prospects of silicon photonics switches operating in the O-band, which is widely used. Sc usThe optical circuit switch presented here is an integrated, non-blocking, switch built on a scalable silicon photonics platform. The switching mechanism is based on vertically movable adiabatic coupler waveguides controlled by micro-electromechanical-system actuators, enabling sub-microsecond.
