OPTICAL SWITCH DEVICE AND DESIGN METHOD THEREFOR

WIPO Patent Application WO/2017/018034

A1

[Problem] To provide an optical switch device and the like capable of synchronizing and outputting/inputting two signals while the circuit size of a matrix switch is kept small. [Solution] With respect to a matrix switch in which N2 2-input 2-output optical switches that are switchable to either a cross or bar state are arranged in a matrix with N rows and N columns, where N is an integer of 2 or more, among 2N pairs of input/output ports formed by pairing an original port and an idle port respectively constituting one and the other of externally connectable two input/output ports in each input/output path of the matrix switch connected with all of the optical switches of the matrix switch being switched to the cross state, half, i.e., N, of the pairs including N of the original ports in the first column of the matrix switch are set as a first input/output pair group, and the remaining half, i.e., N, of the pairs are set as a second input/output pair group.
