Abstract: An optical modulator may include at least one ground electrode. The optical modulator may include at least one signal electrode parallel to the at least one ground electrode. The optical modulator may include at least one waveguide parallel to the at least one ground electrode and the at least one signal electrode. The optical modulator may include a first substrate disposed underneath the at least one ground electrode and the at least one signal electrode relative to a surface of the optical modulator. The optical modulator may include a second substrate disposed underneath at least a portion of the first substrate relative to the surface of the optical modulator. The optical modulator may include a floating conductor disposed between the first substrate and the second substrate.
