Abstract: Systems and methods for reducing read latency by storing a redundant copy of data are described. In one embodiment, the systems and methods include identifying data assigned to be written to a page of a storage device, storing the data in a page of a first die of the storage device, and saving at least one codeword from the data to a page of a second die. In some embodiments, the first die is associated with a first channel of the storage device and the second die is associated with a second channel of the storage device.

Abstract: Systems and methods for limiting performance variation in a storage device are described. Storage devices receive work requests to perform one or more operations from other computing devices, such as a host computing device. Completing the work requests may take a response time. In some embodiments, if the response time of executing the work request exceeds a threshold, the storage device may assign additional computing resources to complete the work request.

Abstract: An optical receiver includes a parasitic current compensation circuit having a reference diode, a sense avalanche photodiode (APD), at least one DC voltage source, and a measurement node. The at least one DC voltage source is configured to generate a first DC bias voltage that varies over time and drives the reference diode, and generates a second DC bias voltage that varies over time and drives the sense APD. A reference parasitic current travels through the reference diode based on the first DC bias voltage. A sense current travels through the sense APD based on the second DC bias voltage and exposure of the sense APD to a light signal. The measurement node receives a sense photocurrent, which is generated by the sense APD in response to the exposure of the sense APD to the light signal, the sense photocurrent including the sense current less the reference parasitic current.

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: 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.
