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.

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: Systems, devices, and methods may use input/output (I/O) apparatus and an optical switching medium to switch, or route, optical data signals. The optical switching medium may include a plurality of optical switching regions. The I/O apparatus may transmit optical data signals to and receive optical data signals from the optical switching medium to provide switching functionality.

Abstract: An apparatus includes a detector and a light source configured to emit light. The apparatus further includes a disk with a set of prisms and that is configured to rotate, arranged to receive and direct the emitted light, and arranged to receive and direct backscattered light. The apparatus further includes a reflecting apparatus with multiple reflective facets and configured to rotate, arranged to reflect the emitted light, and arranged to reflect the backscattered light. A focusing apparatus is arranged to focus the backscattered light from the disk towards the detector.

Abstract: An apparatus includes a plurality of storage media mounted on a rotatable spindle. The apparatus also includes an actuator with at least one actuator arm configured to translate among the plurality of storage media and at least two heads supported on the at least one actuator arm. Each of the at least two heads is configured to communicate with the plurality of storage media.

Abstract: An apparatus includes a detector, a light source configured to emit light, a reflecting apparatus having multiple reflective facets, and a mirror. The reflecting apparatus is configured to rotate around an axis and arranged to reflect the emitted light from the light source and reflect backscattered light. The mirror is arranged to reflect the backscattered light from the reflecting apparatus towards the detector.

Abstract: An apparatus includes a detector, a light source configured to emit light, a plurality of disks, and a focusing apparatus. Each disk includes a set of prisms, and each disk is independently rotatable, arranged to receive the emitted light directly or indirectly from the light source, and arranged to receive backscattered light from an object. The focusing apparatus is arranged to focus the backscattered light from the plurality of disks towards the detector.

Abstract: A paver extension bracket device automates extension and retraction of a paver platform extension to correspond to and be driven by extension and retraction of a pre-existing laterally extendable paver mechanism. The device includes a bracket configured for coupling to a laterally extending paver mechanism of a paver. A post is coupled to and extends from the bracket such that said post is configured for coupling to a paver platform extension such that the paver platform extension is extended and retracted respectively by extension and retraction of the paver mechanism.
