Abstract
It is an object of the present invention to provide an optical switch system using optical interference. An optical switch system () comprises an input part () of an optical signal, a branching part () of the signal, a main Mach-Zehnder waveguide (MZ) (), a first intensity modulator () provided on a first arm () for controlling an amplitude of an optical signal propagating through the first arm (), a second intensity modulator () provided on a second arm () for controlling an amplitude of an optical signal propagating through the second arm (), and a combining part () of the signals outputted from the first arm and the second arm, wherein one or both of the branching part () and the combining part () are X-branched.
