An optical switch (26) comprises an input switching element (12) having a plurality of light input ports (10) and an output switching element (16) having a plurality of light output ports (14). The input switching element (12) comprises a plurality of input optical deflector sets (20), each set consisting of a plurality of optical deflectors (18a, 18b), at each light input port (10). The input optical deflectors in each set are arranged in the incident direction of an optical signal that is input to one of the light input ports. The output switching element (16) comprises a plurality of output optical deflector sets (24), each set consisting of a plurality of optical deflectors (22a, 22b), at each light output port (14). The output optical deflectors in each set are arranged in the emergent direction of an optical signal that is output from one of the light output ports.
