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. 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. Fueled by growing demand for cloud computing applications, such as machine learning, the scale, bandwidth, and power consumption of data center networks continue to increase, and with it, a demand for novel network technologies and architectures. Replacing pluggable transceivers with silicon photonics on the same package as the ASIC, NVIDIA CPO innovations provide 5x better power. These are the pluggable optical modules that convert electrical signals to optical signals and back again. Unlike the ASIC and CPU chips that act as the brains. In this paper we discuss the general architecture of integrated silicon photonic switches by exploiting multi-dimensions in wavelength, polarization, and mode.
