Abstract
An electro-optic modulator, a system including an electro-optic modulator, and a method for producing an electro-optic modulator, which provides improved modulation sensitivity and improved environmental characteristics. The electro-optic modulator, according to the present invention, comprises: a substrate having a surface, the substrate having a first index of refraction, a first optical waveguide and a second optical waveguide, the optical waveguides formed in the substrate and being co-planar, each waveguide having a second index of refraction, each waveguide operable to transmit a light signal, a first electrode disposed on the surface of the substrate between the first and second optical waveguides, the first electrode operable to receive a modulation signal, and a second electrode and a third electrode disposed on the surface of the substrate surrounding the first and second optical waveguides, the second and third electrodes connected to a common potential, whereby the light signal is modulated in accordance with the modulation signal.
