A waveguide electro-optic grating coupler modulator based on a single straight channel waveguide and an interdigital modulation electrode structure on an electro-optic substrate, has been reported. Both single-mode and multimode operations are possible. Preliminary experiments have demonstrated the modulation on a proton exchanged LiNbO3 waveguide device. Modulation performed on other electro-optic waveguides, such as GaAs, LiTaO3, and EO polymers, are also possible.
