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: 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: 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: 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.

Abstract: An active metasurface includes a number of periodically-repeated unit cells arranged on a substrate, each of the unit cells including a high-index dielectric block; a heat source positioned to selectively modulate heat applied to the high-index dielectric block; and an insulating undercut region at an interface between the high-index dielectric block and the substrate.
