Abstract	In this paper, an introduction to the design, fabrication, evaluation, and application of acousto-optic modulators using the Bragg di raction of an optical guided wave in a channel optical waveguide due to a surface acoustic wave is provided. First, the surface acoustic wave mode dependence in the acousto-optic Bragg di raction was discussed by considering the surface acoustic wave power required for the maximum di raction P100 calculated using coupled mode theory and the measured P100 in Ti-di used planar optical waveguides fabricated on LiNbO3 substrates. Next, performances of several devices that the author and the coworkers developed are reviewed. These include a waveguide-type acousto-optic modulator using a tapered crossed-channel proton-exchanged optical waveguide on a 128◦-rotated Y -cut LiNbO3 substrate for an optical wavelength of 1.55 μm, a monolithically integrated tandem acousto-optic modulator in which several waveguide-type acousto-optic modulators are connected in tandem on the same substrate, and a waveguide-type acousto-optic modulator in which laser lights of the three primary colors, red, green, and blue, can be modulated by the same modulator at the same driving frequency.
