Abstract:
A multi-section optical modulator and related method wherein two waveguide arms traverse a plurality of successive modulating sections. A differential drive signal is applied separately to each waveguide arm of each modulating sections in synchronism with the transmission of light along the waveguide arms, effecting a dual differential driving of each section. By suitably selecting the number of modulating sections and the section length, a high modulation bandwidth and a high modulation efficiency may be achieved simultaneously for a given peak-to-peak voltage swing of the drive signal.

Claim (Index 32):
An optical waveguide modulator comprising:\n a waveguide Mach-Zehnder interferometer comprising a first waveguide arm and a second waveguide arm connected optically in parallel; a plurality of modulating subsystems, each comprising:\n a first p/n junction located in the first waveguide arm, a first cathode electrode extending along a length of the first waveguide arm in electrical communication with an n-side of the first p/n junction, and a first anode electrode extending along the length of the first waveguide arm in electrical communication with a p-side of the first p/n junction; \n a second p/n junction located in the second waveguide arm, a second cathode electrode extending along a length of the second waveguide arm in electrical communication with an n-side of the second p/n junction, and a second anode electrode extending along the length of the second waveguide arm in electrical communication with a p-side of the second p/n junction; and, \n a plurality of electrical drive circuits for separately driving the plurality of modulating subsystems, each electrical drive circuit comprising a first differential driver DC coupled to the first cathode electrode and the second cathode electrode of one of the modulating subsystems, and a second differential driver electrically DC coupled to the first and second anode electrodes of the one of the modulating subsystems.
