Abstract: Implementations described and claimed herein provide a high-capacity, high-bandwidth scalable storage device. The scalable storage device includes a layer stack including at least one memory layer and at least one optical control layer positioned adjacent to the memory layer. The memory layer includes a plurality of memory cells and the optical control layer is adapted to receive optically-encoded read/write signals and to effect read and write operations to the plurality of memory cells through an electrical interface.

Abstract: Interference mitigation for a LiDAR system includes identifying a presence or absence of interference from a non-co-located light source in a sample of incident light received by a detector in the LiDAR system. In the absence of interference, a nominal set of reference values is used for one or more spacio-temporal scanning profile trajectory parameters. Scanner components of the LiDAR system are controlled using the nominal set of reference values. In the presence of interference, the nominal set of reference values is augmented to modify the spacio-temporal scanning profile trajectory parameters. Scanner components of the LiDAR system are controlled using the augmented set of reference values to avoid detection of and interference by the non-co-located light source.

Abstract: An active metasurface includes a number of periodically-repeated unit cells arranged on a substrate that each include a plasmonic waveguide shaped and sized to provide a cutoff mode that captures light of a target wavelength. The active metasurface includes an index modulation controller that controllably varies a voltage differential across each one of the periodically-repeated cells to change a phase of light incident on the metasurface.

Abstract: An active metasurface that provides low-loss and high-bandwidth modulation control of light includes a number of cells arranged on a substrate. A controller dynamically alters a voltage differential supplied to the electrodes of each of the cells is adapted to alter refractive index of each of the high-index dielectric blocks in order to controllably steer light exiting the cell.

Abstract: LiDAR optical paths, particularly in co-located emitter/receiver path configurations, can introduce unintended and unwanted reflections due to mirrors, lenses, and/or enclosure materials or glass that can fall on one or more photosensors. These un-desirable signals can cause significant disruptions in output amplifier biasing and/or severe channel saturation. Autonomous vehicle LiDAR is particularly challenging as packaging requirements require complex optics to direct the laser source; the target size, shape, and relative velocity, and distance to the autonomous vehicle are unknown; and the location of the target objects within range are potentially rapidly changing over time. The presently disclosed dual photodiode LiDAR systems are used to separate and compensate for errors introduced by LiDAR optics to improve the accuracy and reliability of LiDAR systems, including but not limited to autonomous vehicle LiDAR systems.

Abstract: Various implementations of a LiDAR system disclosed herein include two laser sources configured to generate a first laser beam and a second laser beam, a first vertically scanning mirror configured to rotate about a first axis, a second vertically scanning mirror configured to rotate about a second axis, wherein the first axis and second axis are in the same plane and may be parallel to each other, and a polygonal mirror configured to rotate around a third axis, wherein the third axis is orthogonal to each of the first axis and the second axis, wherein the first vertical scanning mirror is configured to direct the first laser beam towards the polygonal mirror and the first vertical scanning mirror is configured to direct the first laser beam towards the polygonal mirror. Alternative implementations may include a combination of collection lenses and detectors to detect reflected laser beams.
