Abstract
An optical waveguide is described. This optical waveguide may be defined in a semiconductor layer, and may include a vertical slot that includes an electro-optic material having an electric-field-dependent index of refraction, and the electro-optic material may be other than a semiconductor in the semiconductor layer. Alternatively, the optical waveguide may include a vertical stack with two semiconductor layers that surround and partially overlap an intermediate layer, which includes the electro-optic material.
