<p>In an optical switch apparatus made to successively carry out the route switching with respect to frame signal light inputted through various paths while eliminating the dispersion of an output power value, input side deflecting units 31 to 3n are disposed in corresponding relation to a plurality of input ports and output side deflecting units 41 to 4n are disposed in corresponding relation to a plurality of output ports, and each input side deflecting unit 31 to 3n and each output side deflecting unit 41 to 4n are constructed in a manner such that a plurality of optical deflecting elements 311, 312, 411 to 413 made to deflect signal light in response to an electric field applied are arranged in a cascade fashion, and the optical deflecting element 311, 312, 411 to 413 constituting the input side deflecting unit 31 to 3n or the output side deflecting unit 41 to 4n is made so as to variably adjust the level of signal light to be outputted from the output side deflecting unit 41 to 4n to the output port.</p> |
