摘要: An optical switch matrix for selecting an optical propagation route between input ports and output ports by electric control. A first directional coupler is disposed on the input port side of a crosspoint of the matrix. A second directional coupler is disposed on the output port side of the crosspoint. A corner reflector is formed at a joint of the first and second directional coupler.
