ABSTRACT:
To provide an optical switcher capable of sending incident light on one input port to any plurality of output ports. The optical switcher includes input ports disposed on extensions of m input optical paths (m being 2 or greater natural number), output ports disposed on extensions of n output optical paths (n being 2 or greater natural number), and movable translucent switch mirrors311-3mn, disposed at intersections of the m input optical paths and the n output optical paths, for switching between the input optical paths and the output optical paths. A switch mirror311-3mnlocated nearer the input ports has a higher transmittance.
