摘要： A two-dimensional waveguide light multiplexer can efficiently multiplex and distribute a light signal in two dimensions. An example of a two-dimensional waveguide light multiplexer can include a waveguide, a first diffraction grating, and a second diffraction grating arranged such that the grating direction of the first diffraction grating is perpendicular to the grating direction of the second diffraction grating. In some examples, the first and second diffraction gratings are on opposite sides of a waveguide. In some examples, the first and second diffraction gratings are on a same side of a waveguide, with the second grating over the first grating.

摘要： A self-seeded optical parametric amplifier (OPA) system includes a cavity mirror, a wavelength conversion unit, and a dichroic filter. The cavity mirror is configured to allow high transmission for an input laser beam and high reflection for a feedback beam. The wavelength conversion unit is configured to convert the input laser beam into a signal laser beam and an idler laser beam. The dichroic filter is configured to allow one of the signal laser beam and the idler laser beam to pass through the dichroic filter and reflect the other one onto a feedback path.

摘要： 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.

摘要： 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.

摘要： A near-eye optical display system utilized in augmented reality devices includes a see-through waveguide display having optical elements configured for in-coupling virtual images from an imager, exit pupil expansion, and out-coupling virtual images with expanded pupil to the user's eye. The near-eye optical display system further includes a curved two-sided array of electrically-activated tunable liquid crystal (LC) microlenses that is located between the waveguide and the user's eye. The LC microlenses are distributed in layers on each side of the two-sided array. Each pixel in the waveguide display is mapped to an LC microlens in the array, and multiple nearby pixels may be mapped to the same LC microlens. A region of the waveguide display that the user is gazing upon is detected and the LC microlens that is mapped to that region may be electrically activated to thereby individually shape the wavefront of each pixel in a virtual image.
