Abstract
An electro-optic device including an optical waveguide formed in an electro-optic material that propagates an optical signal along a first direction of propagation is described. The device also includes an electrical waveguide formed in the electro-optic material and positioned co-linear relative to the optical waveguide and in electromagnetic communication with the optical waveguide, where the electrical waveguide also propagates the electrical signal in the first direction of propagation. A compensation network is electrically coupled to the electrical waveguide at a junction and propagates the electrical signal in a second direction of propagation that is substantially non-co-linear with the first direction of propagation. In operation, the compensation network modifies at least one of a phase or an amplitude of the electrical signal at the junction relative to a phase or an amplitude of the accumulated modulation on the optical signal at the junction, respectively, and then returns the modified electrical signal to the electrical waveguide.
