The splitter unit, the first waveguide, the second waveguide, and the directional coupler unitform an optical interferometer that branches an input light and causes the branched lights to interfere. The first liquid-crystal celland the second liquid-crystal celltransmit the lights branched in the optical interferometer and delay the lights according to applied signals, respectively.
