Multiport optical switches integrated on Si photonics platform

抄録

This paper reviews recent progress in integrated multiport optical switch, fabricated on silicon-on-insulator wafers. Typical topologies of multiport switch and the element switches are first described. Then, we review pioneering studies of the integrated multiport switches. We also describe feasible improvements, some of which will better fit the switch to a real use in telecommunication and some to enlarge the port count.
