Abstract
Structures for an electro-optic modulator and methods of fabricating a structure for an electro-optic modulator. An electro-optic modulator is arranged over a portion of a waveguide core. The electro-optic modulator includes an electrode, an active layer arranged adjacent to the electrode, and a dielectric layer including a portion that has a lateral arrangement between the electrode and the active layer. The active layer is composed of a material having a refractive index that is a function of a bias voltage applied to the electrode and the active layer.
