1. An electro-optic device, comprising:
an intensity modulator (IM) residing on a substrate;
a first phase modulator (PM) optically coupled to the IM and residing on the substrate;
a second PM optically coupled to the first PM, the IM, the first PM, and the second PM sharing a waveguide structure including lithium, the second PM residing on the substrate; and
a continuous integrated electrode structure on the substrate, the continuous integrated electrode structure including a first electrode structure for the IM, a second electrode structure for the first PM, and a third electrode structure for the second PM, the first electrode structure extending through the IM but not extending through the first PM or the second PM;
wherein the IM, the first PM, and the second PM are driven by at least one RF source providing an RF signal, the RF signal being provided to the IM, the first PM, and the second PM by the continuous integrated electrode structure.
