Document Type and Number:
WIPO Patent Application WO/2007/063871
Kind Code:
A1
Abstract:
[PROBLEMS] To provide an optical switch system by optical interference. [MEANS
FOR SOLVING PROBLEMS] An optical switch system (1) comprises an input section
(2) of an optical signal, a main Mach-Zehnder waveguide (MZC)(7),
a first intensity modulator (9) provided on a first arm (4) for controlling the
amplitude of an optical signal propagating on the first arm (4), and a second intensity
modulator (10) provided on a second arm (5) for controlling the amplitude of an
optical signal propagating on the second arm (5), wherein one or both of a branch
portion (3) and a multiplexing portion (6) are X-branched.
