Abstract: An electro-holographic light field generator device comprises surface acoustic wave (SAW) optical modulators arranged in different directions. Specifically, some embodiments have SAW modulators arranged in pairs, nose-to-nose with each other, and have output couplers that provide face-fire light emission. These SAW modulators also possibly include SAW sense transducers and/or viscoelastic surface material to reduce crosstalk.

Abstract: A steerable optical transmit and receive terminal includes a MEMS- based Nx1 optical switch network. Each optical switch (1218 - 1226) in the optical switch network uses an electrostatic MEMS structure to selectively position a translatable optical grating (1402) close to or far from an optical waveguide (1410). In the close ("ON") position, light couples between the translatable optical grating (1402) and the optical waveguide (1410), whereas in the far ("OFF") position, no appreciable light couples between the translatable optical grating (1402) and the optical waveguide (1410). The translatable optical grating (1402) is disposed at or near a surface of the optical switch network. Thus, the translatable optical grating emits light into, or receives light from, free space. The steerable optical transmit and receive terminal also includes a lens (2312) and can steer a free space optical beam in a direction determined by which port (2306) of the Nx1 optical switch network is ON.

Abstract: A light steering system and method for diffractive steering of electromagnetic radiation such as visible light is disclosed. Embodiments of the light steering system include leaky-mode SAW modulators as light modulator devices. The SAW modulators preferably include reflective diffractive gratings. The gratings are mounted to/patterned upon an exit face that opposes an exit surface of the SAW modulator, in one example. Steering of light signals emitted from the SAW modulators in these systems can be accomplished by varying wavelength of light signals introduced to the SAW modulators, and/or by varying frequency of RF drive signals applied to the SAW modulators. In addition, light field generators that incorporate SAW modulators of the proposed light steering system within displays of the light field generators are also disclosed.

Abstract: Electro-holographic light field generator devices comprising surface acoustic wave (SAW) optical modulators are disclosed that employ multiple output couplers. These output couplers might be distributed along waveguides of the SAW modulators, within output coupling regions. Each of these output couplers can be configured for directing an incident leaky mode light at different output angles. In some cases, it may be desirable to employ the output couplers to function as different sub-pixels, to provide light to different viewing directions. The output couplers may be mirrors, volume gratings, chirped gratings, reflection gratings, two dimensional gratings, and/or transmission gratings. The output couplers may be angled so that the coupling output fans for each optical modulator are offset from the waveguide for that optical modulator.

Abstract: An optical neurostimulation and detection system and method are disclosed. The system includes a medical device including an implantable body, and a stimulation controller that connects to the medical lead device and provides a light source. One or more light emitter modules of the lead body couple light signals of the light source into modulated light signals, and the modulated light signals are emitted through the one or more light emitter modules to stimulate neural cells and/or neural tissue of a subject. In a preferred embodiment, the light emitter modules include a surface acoustic wave (SAW) transducer that couples the light source into the modulated light signals. Such a system provides emitted light incident upon the neural tissue of a much higher resolution than current systems and methods and can provide long-term implantation with fewer side effects and less tissue damage than current systems and methods.

Abstract: An electro-holographic light field generator device is disclosed. The light field generator device has an optical substrate with a waveguide face and an exit face. One or more surface acoustic wave (SAW) optical modulator devices are included within each light field generator device. The SAW devices each include a light input, a waveguide, and a SAW transducer, all configured for guided mode confinement of input light within the waveguide. A leaky mode deflection of a portion of the waveguided light, or diffractive light, impinges upon the exit face. Multiple output optics at the exit face are configured for developing from each of the output optics a radiated exit light from the diffracted light for at least one of the waveguides. An RF controller is configured to control the SAW devices to develop the radiated exit light as a three-dimensional output light field with horizontal parallax and compatible with observer vertical motion.

Abstract: Acousto-optical modulators, such as a SAW modulators, with telescope arrays and superimposed volume gratings for light field generation are disclosed. These devices can employ pixelated demagnification and have layers of output optics, such as reflective gratings and/or arrays of transmissive refractive or diffractive lenses that manipulate the light emitted by the SAW modulator. In other cases, superimposed volume gratings are used, in which pixilation occurs in angle space.

Abstract: A system and method for light field generation is disclosed. A proposed holographic display system encodes views of a scene into surface acoustic waves (SAW signals) that propagate along waveguides of SAW modulators and/or optical signals propagating in the waveguides. Each view provides a different perspective of the scene when the views are projected as light fields out of the SAW modulators and are viewed at different locations by an observer. In some examples, the system encodes the brightness information for each view into the light signals.
