Abstract
Structures for an electro-optic modulator and methods of fabricating a structure for an electro-optic modulator. The electro-optic modulator is arranged over a portion of a first waveguide core. The electro-optic modulator may include an electrode, an active layer, a second waveguide core, and a dielectric layer that is arranged between the active layer and the second waveguide core. The active layer is composed of a material having a refractive index that is a function of a bias voltage applied between the electrode and the first waveguide core.
