This abstract first appeared for US patent application 18665091 titled 'OPTICAL MODULATOR AND METHOD OF MANUFACTURING AN OPTICAL MODULATOR
Original Abstract Submitted
An optical modulator includes a first Mach-Zehnder modulation portion including a first waveguide and a second waveguide, a second Mach-Zehnder modulation portion including a third waveguide and a fourth waveguide, a third Mach-Zehnder modulation portion optically coupled to the first Mach-Zehnder modulation portion and the second Mach-Zehnder modulation portion. The third Mach-Zehnder modulation portion includes a fifth waveguide including an input end optically coupled to an output end of the first waveguide, a sixth waveguide including an input end optically coupled to an output end of the second waveguide, a seventh waveguide including an input end optically coupled to an output end of the third waveguide, an eighth waveguide including an input end optically coupled to an output end of the fourth waveguide.
