ABSTRACT:
A surface acoustic wave generator is provided on an optical waveguide layer of an acousto-optical material. A group of parallel light beams each made significant according to the position of the path of propagation of light are made incident on the waveguide layer at an angle satisfying the Bragg diffraction condition with respect to a surface acoustic wave, and are successively diffracted by the wave, whereby a digital amount represented by the presence of light beams of the group is converted to an analog amount in terms of the power of light.
