Abstract
The slowdown of Moore's law poses challenges for scaling data center networks using electrical packet switches. Optical circuit switching (OCS) offers a solution by eliminating the need for transceivers and electrical switches. This paper demonstrates ultrafast OCS based on a microcomb and semiconductor optical amplifiers (SOAs), achieving sub-nanosecond switching with 25-Gbps NRZ and 50-Gbps PAM-4 burst mode data transmission.
