Hafnia and silica film structures deposited by electron-beam evaporation
Background Striated composite materials (SCM) are of interest since the material properties of the composite are different than those of the constituent materials, and they are a potential technique to create modified material mixtures with high laser-induced–damage thresholds. This approach has been successfully demonstrated for ion-beam-sputtered...

Hydrogen production via electrogenic bacteria by respiration of colloidal quantum dots
Background Hydrogen and other fuels can be produced by living bio-nano systems which combine microorganisms and nanomaterials. Typically, these systems use light absorbed by nanomaterials to provide high-energy electrons (via an electron transfer process) for microbial metabolic processes yielding a biosynthetic solar fuel such as hydrogen. However,...

Ultralow SwaP Photonic Integrated Spectrometer
Background On-chip spectrometers pose many advantages over other types of state-of-the-art spectrometers, which typically consist of large and bulky free space optical components. Small chips significantly reduce size, weight, and power (SWaP) and contain no moving parts, may include radiation-hardened materials, are much easier to shield from radiation...

Titanium oxide coatings drastically reduce thermal effects in Lithium Niobate
ProblemLithium niobate (LN), possessing wide transparent window, strong electro-optics effect and large second/third- order nonlinearities, is an ideal material platform for integrated photonic applications. Microring resonators are particularly suitable as integrated photonic components, given their flexibility of device engineering and their potential...

Freeform and Nanostructured Surfaces Based Augmented Reality Sunglass Display
A near eye display includes at least one of a combiner, a secondary mirror, and a waveguide having a freeform nanostructured surface. The freeform nanostructured surface encompasses a freeform surface, a nanostructured surface or a combination of both the freeform surface and the nanostructured surface. The freeform nanostructured surface can be incorporated...

Optomechanical Disk Vibratory Gyroscopes
Patent AbstractAn integrated optomechanical disk vibratory gyroscope device includes a mechanical oscillator having a substantially circular structure. The substantially circular structure is supported by a pillar, and mechanically isolated from a surrounding structure by a gap or slot. One or more actuators are coupled to the mechanical oscillator...

Cheap, Plentiful, and Environmentally Friendly Method for Producing Hydrogen
Background Dominant methods to make hydrogen require fossil fuels such as natural gas. Renewable approaches to hydrogen production have employed expensive precious metal catalysts like platinum which are too costly to be commercially viable and/or chromophores which often require non-aqueous solutions and exhibit short decomposition lifetimes. Technology...
