Abstract:
In an optical switch array on which optical switches that require individual electric wires are integrated, the present invention provides an optical switch array and a multi-cast switch in which the electric wires are shortened by optimizing the arrangement of the optical circuit portion. In the optical switch array in which three arrays of 1×4 switch circuits are disposed in parallel, the position where each optical switch is disposed is sequentially shifted by Dy in the y axis direction. That is, in the case where an adjacent 1×4 optical switch circuit exists on both sides, the 1×4 optical switch located there between is located at the center of the two 1×4 optical switch circuits, which are adjacent in the y axis direction. Each of the three 1×4 optical switch circuits that are arrayed are disposed at a position shifted from the adjacent 1×4 optical switch circuit by Dy in the y axis direction, in accordance with the positional coordinate in the x axis direction, and the electric wires at the ground side are shared such that each optical switch circuit is located sequentially shifted by Dy in the −y axis direction.
