Abstract

A photonic modulator includes a first electro-optical waveguide, the first electro-optical waveguide having a first electro-optical waveguide side and a second electro-optical waveguide side opposite the first electro-optical waveguide side, a second electro-optical waveguide, the second electro-optical waveguide having a third electro-optical waveguide side and a fourth electro-optical waveguide side opposite the third electro-optical waveguide side, a first driven radio frequency electrode coupled to the first electro-optical waveguide side, a second driven radio frequency electrode coupled to the third electro-optical waveguide side, and a floating electrode coupled to the second electro-optical waveguide side and coupled to the fourth electro-optical waveguide side. The second electro-optical waveguide side and the third electro-optical waveguide side face each other and are spaced apart from one another.
