Photonic FPGA platform to create arbitrary photonic devices by programming the device structure into the platform.

Background The development and design process for electronic integrated circuits is very intensive before a finalized chip design is sent to the chip fab. Most application-specific electronic integrated circuits require a prototyping process that can be accomplished with a field-programmable gate array (FPGA), an electronic circuit which can be reconfigured...

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-coated Lithium Niobate

Background Microring resonators are particularly suitable as integrated photonic components given their flexibility of device engineering and potential for large-scale integration, but their susceptibility to temperature fluctuation has become a major challenge for their implementation in a practical environment. The realization of lithium niobate...

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...

Method for Nano-Structuring Metal Surfaces by Femto-Second Laser Machining

This is a process using a femto-second laser, which produces nanostructures with high surface area on metals such as Ti, Pt, Au, Cu, Al, W. The method can dramatically alter the surface reflectivity rendering the metals black, or can be controlled to produce unexpected colors. For example, platinum and aluminum can be made to appear gold, gray, or black.Applications:The...
