Abstract
An optical waveguide modulator is disclosed which uses single crystals of TlGaSe.sub.2 or TlInS.sub.2. The optical waveguide modulator is used to impress a signal upon a light beam traveling in a waveguide. Monochromatic light is guided along a thin plate of the crystal. Acoustic waves are generated which move across the thickness of the crystal, modulating the light. The frequency, polarization, or mode of the light can be modulated by the acoustic waves.
