Abstract: An optical modulator is disclosed, in which a MMI couplers are used for input signal splitting for branching into individual Mach-Zehnder interferometers, as well as for branching and combining from individual Mach-Zehnder waveguides. MMI couplers, splitters, and combiners may be cascaded and combined with single-mode Y-splitters and combiners to provide modulators of various types, including dual polarization, quadrature phase Mach-Zehnder interferometer base optical modulators.

Abstract: A planar optical waveguide circuit includes an optical modulator, such as that based on a Mach-Zehnder interferometer, that is followed by an in-line optical tap in the form of a 2×2 multi-mode interference coupler that is characterized a reduced tracking error as compared to Y-junction couplers.
