    • An interference optical switch capable of switching in a wide band, having a high extension ratio and produced with a large production tolerance and an optical switch module. As optical multiplexing/demultiplexing means, a phase generation coupler (111) the output of which involves a phase difference having wavelength dependence is used. The total sum 2pi{Phi1(lambda)+ PhiDeltaL(lambda)+Phi2(lambda)} of the phase difference Phi1(lambda) of the light outputted from the phase generation coupler (111), the phase difference PhiDelta L(lambda) due to the optical path length difference of an optical path length difference imparting section (131), and the phase differencePhi2(lambda) of the light outputted from a directional coupler (153) is constant independently of wavelength. Thus, an interference optical switch independent of wavelength is realized.
