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: 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 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 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.
