Abstract
A first (second) electrical input port receives a first (second) drive signal. A first (second) transmission line is configured to propagate a first (second) electromagnetic wave over at least a portion of a first (second) optical waveguide arm of an MZI to apply an optical phase modulation. A drive signal interconnection structure is configured to provide a first electrical connection between the first electrical input port and an inner electrode shared by the transmission lines, and a second electrical connection between the second electrical input port and respective outer electrodes of the transmission lines; and is configured to preserve relative phase shifts between the drive signals. An impedance associated with a first electric field distribution between the inner electrode and a first of the outer electrodes is substantially equal to an impedance associated with a second electric field distribution between the inner electrode and a second of the outer electrodes.
