Abstract: Aspects of the subject disclosure may include, for example, system, comprising a substrate having an interconnect in or on a surface of the substrate, a riser disposed over the surface, the riser being configured with one or more through riser vias for coupling to the interconnect, a device positioned over the surface, the device having one or more conductive contacts residing in a plane of the device, and one or more wire bonds coupling the one or more through riser vias with the one or more conductive contacts thereby enabling connectivity of the interconnect to be raised toward or to the plane of the device such that at least one of the one or more wire bonds has a limited physical length.

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.
