Abstract:
1. An optical amplitude modulation system comprising: a Mach-Zehnder waveguide, the Mach-Zehnder waveguide comprising: a first intensity modulator provided on the first arm, the first intensity modulator controlling amplitude of the optical signal propagating through the first arm; a second intensity modulator provided on the second arm, the second intensity modulator controlling amplitude of the optical signal propagating through the second arm; a first electrode (electrode A) of the first intensity modulator; a second electrode (electrode B) of the second intensity modulator; a third electrode (electrode C) controlling a phase difference between the optical signal propagating through the first arm and the optical signal propagating through the second arm, a modulation signal being applied to the third electrode; and a signal source part, the signal source part comprising:
