Abstract: An optical guided wave modulator and digital deflector is described having a piezoelectric substrate with an amorphous film waveguide thereon. An interdigital periodic electrode structure is connected to the amorphous film and to a source of d.c. voltage. The voltage produces fringing fields which generate a periodic strain in the piezoelectric substrate. The compressional strain in the piezoelectric substrate extends into the amorphous film to produce a periodic variation of index of refraction which functions as a grating at the Bragg angle which deflects an optical wave traveling in the amorphous film.

Abstract: Couplers are disclosed for use with guided elastic waves and guided optical waves. The coupling is effected by means of a coupling region having a different phase velocity characteristic than that of the waveguide. The presence of the coupling region causes the waves traveling in the waveguide to become highly leaky. These leaky waves then encounter a second waveguide or transducer and are coupled into it. Utilizing the electroacoustic effect in the acoustic wave devices and the electrooptic effect in the optical wave devices, the phase velocity characteristic of the coupling region is controllable, permitting switchable couplers.

Abstract: A tunable optical filter suitable for use in integrated optical circuits including the combination of a substrate having an optical waveguide such as a thin film thereon. Means such as an optical fiber or grating is provided for introducing light waves in a first mode into the waveguide. An acoustic transducer driven by a tunable electronic signal source is used to propagate acoustic waves on the surface of the waveguide. The optical and acoustic waves interact to produce another optical wave having a mode different than the original optical wave when phase matching conditions are satisfied. A mode filter is located in the waveguide to block the original optical wave and pass the second optical wave.

Abstract: A charge electrode array for use in an ink jet printing apparatus is formed by anisotropic etching of apertures through a single crystal silicon substrate of (110) orientation. Conductive diffusion layers in the walls of and adjacent to the apertures permit a charge to be placed on a jet stream passing through the apertures. Contacts can be formed on the adjacent diffusion layers to provide connection to an externally located charging circuit or the contacts may be omitted when the charging circuit is formed in the substrate itself and connected by diffusion or a metal layer to each adjacent diffusion layer. Jet nozzles and synchronization electrodes are shown incorporated in the charge electrode array to form a monolithic structure capable of performing a plurality of functions. Substrate contacts are also provided for biasing.

Abstract: A xerographic printer/copier includes a photoconductor drum (4), means for producing a latent image, from an original document, on the drum and a laser beam scanning system (24, 25, 28 and 27) normally employed to produce such a latent image in response to input digital data. The system also includes a detector (30) placed adjacent the photoconductor drum at the laser scanning position. This detector is employed to produce signals representing a latent image on the drum produced by sensing the change in charge on the drum when the latent image is scanned by the laser beam (26) in an unmodulated condition.
