Abstract: An integrated optical beam steering system is configured in three stages to provide beam steering for image light from an imager (e.g., laser, light emitting diode, or other light source) to downstream elements in a display system such as an exit pupil expander (EPE) in a mixed-reality computing device. The first stage includes a multi-level cascaded array of optical switches that are configurable to spatially route image light over a first dimension of a two-dimensional (2D) field of view (FOV) of the display system. The second waveguiding stage transfers the image light along preformed waveguides to a collimator in the third stage which is configured to collimate the image light along the first dimension of the FOV (e.g., horizontal). The waveguiding and collimating stages may be implemented using lightweight photonic crystal nanostructures.

Abstract: A semiconductor device includes a floating gate that can be charged in a nonvolatile manner. The floating gate is also structured as an optical waveguide, and maybe optically coupled to a photonic circuit, such as an interferometer.

Abstract: A dual path configuration Integrated LiDAR architecture can contain a focal plane transmitter and a focal plane coherent receiver. The integrated LiDAR transmitter can contain an optical frequency chirp generator and a focal plane optical beam scanner with integrated driving electronics. The integrated LiDAR receiver architecture can be implemented with per-pixel coherent detection and amplification.
