<Multicast Switch Optical Computing>

 Our group have previously demonstrated several versions of micro-electromechanical-system (MEMS)-based silicon photonic switches. They have desirable characteristics. However, those switches provide 1-to-1 connections only, like most of other optical switches. In many applications that require high bandwidth interconnects between one source to multiple destinations, such as video streaming servers and video conference systems, multicast optical switches are desirable. Some multicast silicon photonic switches have been reported. However, the scale of the switch is small or it has unnecessary high excess optical loss due to its architecture. We reported on a silicon photonic MEMS switch capable of multicasting.
