    Abstract: Disclosed are differential-drive electro-optic modulator structures for linear electro-optic (Pockels) platforms such as thin-film LiNbO3 (TFLN), directly compatible with traditional differential-output analog drivers, such as a linear electro-optic modulator, including: a first signal trace; a second signal trace, wherein the first signal trace and the second signal trace are driven by a differential signal; a first optical arm; and a second optical arm, wherein a geometry of the first signal trace and the second signal trace causes the differential signal to modulate optical signals in the first optical arm and the second optical arm, such that when the optical signals are combined to create a resultant optical signal, the geometry mitigates chirp in the resultant optical signal. Other embodiments are disclosed.

    Abstract: An optical waveguide structure forms an MZI in proximity to an electro-optic material. A first (second) electrical input port is configured to receive a first (second) drive signal. The second drive signal has a negative amplitude relative to the first 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 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 electrode shared by the transmission lines, and a second electrical connection between the second electrical input port and respective electrodes of the transmission lines; and is configured to preserve relative phase shifts between the drive signals. Input impedances at the first and second electrical input ports are substantially equal to each other.

    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.
