摘要： A high-efficiency electro-optic modulator with an equalized frequency response is described. The modulator includes an optical waveguide formed in an electro-optic material that propagates an optical signal along a first direction of propagation. An electrical waveguide is formed on the electro-optic material and positioned generally co-linear relative to the optical waveguide and in electromagnetic communication with the optical waveguide. The geometry of the electrical waveguide is selected to achieve a modulation efficiency at a frequency in a bandwidth of a digital spectrum. A compensation network is electrically coupled to the electrical waveguide at a junction. The compensation network reduces an electro-optic response of the electro-optic modulator below the mean frequency bandwidth of the digital spectrum, thereby causing an increase of the electro-optic response above the mean frequency of the digital spectrum.
