Abstract: Disclosed herein is a system for detecting rotational speed and early failures of an electronic device. The system includes a rotating disk affixed to a rotating shaft of the electronic device. The rotating disk has projections extending from its periphery. A time of flight ranging system determines distance to the projections extending from the rotating disk. Processing circuitry determines a rotational speed of the rotating shaft from the determined distances to the projections extending from the rotating disk, and detects whether the electronic device is undergoing an early failure from the determined distances to the projections extending from the rotating disk. Rotational speed is determined from the time between successive peaks in the determined distances, and early failures (for example, due to wobble of the shaft) are determined where the peaks vary unexpectedly in magnitude.

Abstract: Modulating graphene's optical conductivity with an electrolyte nanopatterning technique reduces or eliminates scattering loss caused by rough edges from etching. This technique uses a resist mask patterned with features as small as 30 nm to shield graphene from ions in an electrolyte. It can provide a carrier density variation of about 1014 cm?2 across a length of just 15 nm. And it can be combined with a technique of growing or transferring graphene on atomically smooth hexagonal boron nitride (hBN) to increase graphene's carrier mobility, e.g., to 10,000 cm2/(V·s) or more. The resulting graphene metamaterials can be used to make voltage-tunable electro-optical devices, such as beam-steering devices, electro-optical switch and modulators, and reconfigurable holograms.

Abstract: A reflective spatial light modulator (SLM) made of an electro-optic material, such as barium titanate, in a one-sided Fabry-Perot resonator can provide phase and/or amplitude modulation with fine spatial resolution at speeds over a Gigahertz. The light is confined laterally within the electro-optic material/resonator layer stack with microlenses, index perturbations, or by patterning the layer stack into a two-dimensional (2D) array of vertically oriented micropillars. Alternatively, a photonic crystal guided mode resonator can provide vertical and lateral confinement of the resonant mode. In phase-only modulation mode, each pixel in the SLM can produce a ? phase shift under a bias voltage below 10 V, while maintaining nearly constant reflection amplitude. The methodology for designing this SLM could also be used to design other SLMs (for example, amplitude-only SLMs).
