Paper Abstract

We report here a new waveguide electrooptic grating coupler modulator based on a tooth-shaped modulation electrode structure and a single straight channel waveguide on an electrooptic substrate. An electrooptically-induced grating on the channel waveguide couples the propagating single or multimode lights into the substrate, and thus achieves intensity modulation of the guided modes. Both single-mode and multimode operations are possible. Preliminary experiments have demonstrated the effect of modulation on a proton exchanged LiNbO3 waveguide device. Modulation on other electrooptic waveguides are expected.
