Abstract: A light detection and ranging system can have a metasurface that continuously extends between a pair of electrical contacts. The metasurface may be separated from an underlying silicon substrate by an air gap with the silicon substate doped with a P-i-N configuration to create electrostatic force that alters a size of the air gap in response to a voltage bias between the pair of electrical contacts.

Abstract: A device includes a substrate an array of disk-shaped structures arranged above the substrate. Each disk-shaped structure includes an aperture filled with an optoelectrical material. A method includes passing a light beam through a metasurface. The method also includes varying voltage applied to the metasurface to change a phase of the light beam to steer the light beam in a two-dimensional pattern.

Abstract: Apparatus and method for transferring data in a data storage system, such as but not limited to a hard disc drive (HDD). An optical link is provided between an analog front end (AFE) of a data storage device controller circuit (SOC) and a preamplifier/driver circuit (preamp) mounted to a rotary actuator to transfer an analog domain signal. A selected component is extracted from the signal using a modulation element such as a micro-resonance ring (MRR) or a Mach-Zehnder Interferometer Modulation (MZM) device. The extracted component is forwarded to a processing circuit to facilitate a transfer of data between a local memory and a non-volatile memory (NVM). The optical link includes a flexible portion in a flex circuit affixed to the rotary actuator and which supports the preamp. Multiplexed read, write, and power control signals are concurrently transmitted via the optical link. The link can concurrently service multiple head-disc assemblies (HDAs).

Abstract: Method and apparatus for generating and controlling pulses in a light detection and ranging (LiDAR) system. An opto-mechanical phase shifter (OMPS) device has an array of unit cells supported by a semiconductor substrate. Each unit cell includes a resonator extending between opposing first and second doped regions and a flexible layer extending above the resonator separated by an intervening gap. Application of voltage across the doped regions establishes an electric field that extends through the resonator and controllably deforms the flexible layer to direct a beam of light in a desired direction and with a desired phase. A detector derives range information associated with a target illuminated by the directed beam of light. The derived range information can be used to adjust the voltage(s) applied to the OMPS device. Each unit cell can be independently activated and controlled, or groups of unit cells can be operated as a set.

Abstract: A light detection and ranging system can employ a metal insulator metal tunnel junction positioned atop a substrate. Activation of the metal insulator metal tunnel junction by a signal from a controller can generate light via inelastic scattering. Light to be used to detect downrange targets can be combined from multiple junctions via a multimode interference combiner.
