Abstract
An optical signal switch identifies the routing of each optical packet, directs each packet arriving at any input to the output corresponding to the routing, and includes delay lines through which the optical signals pass selectively. The switch has three stages: a first stage directing each optical packet received at an input to a chosen delay line, a second stage coupled to the output of the delay lines to direct the optical packets selectively to the output corresponding to the determined routing, and an output third stage.
