Abstract: An acousto-optic deflector includes a body of material through which a laser beam to be modulated passes. The material has an acoustic attenuation in the range of 0.15 to 1.0 dB/?s-GHz2 and operates in a UV range of about 150 to 400 nm. A transducer is bonded to the body of material to launch a wave. An electronic driver drives the transducer.

Abstract: An optic modulator implemented on a substrate that is conductive to light and which includes a pair of light waveguides formed on the substrate is described. The waveguides extend substantially coextensively with one another and are separated from one another by a transverse distance that gradually varies along the courses of the waveguides. The waveguides are arranged to pass between an outer electrode assembly and a center electrode assembly. The outer electrode assembly substantially surrounds the center electrode assembly in such a manner as to create an electric field between the center electrode assembly and the outer electrode assembly when a voltage is applied across the outer and center electrode assemblies.
