Abstract: Optical devices including deterministic aperiodic patterning using spiral arrays exhibit circular symmetry in continuous Fourier space via polarization-insensitive planar diffraction. Far-field diffractive coupling in these structures leads to the formation of scattering resonances with circular symmetry and characteristic vortex behavior carrying orbital angular momentum. Plasmonic nanoparticle arrays with aperiodic spiral geometry can be used in fabrication of optical devices that benefit from polarization insensitive, enhanced light-matter coupling on planar surfaces, such as thin-film solar cells (enhanced light absorption and efficiency), photodetectors (enhanced light emission and efficiency), optical biosensors, and polarization devices.

Abstract: Disclosed is a net radiometer that measures the net difference between incoming solar and outgoing terrestrial radiant flux energy in the combined short-wave and long-wave far infrared spectral range. In accordance with principles of the invention, a balanced net radiometer can be constructed where each thermal absorber is formed from two separate pieces joined together to form a single thermal mass. Within each thermal absorber, each piece is coated with a separate surface coating of different spectral sensitivity. By constructing an absorber from two separate pieces, it is possible to apply spectral coatings with different curing characteristics, to thermal absorber that acts as a single thermal mass. The pieces within each thermal absorber are sized in a proportion that thermally balances the absorber's thermal sensitivity between short-wave and long-wave far infrared radiant energy.

Abstract: An apparatus, system, and method are disclosed for nonlinear optical surface sensing with a single thermo-electric detector. In particular, the system includes at least two signal sources that are co-aligned to propagate photons to the same location on a surface. The system also includes at least one focusing element that focuses a sequence of photons that is reflected from the location on the surface. In addition, the system includes at least one frequency selective electromagnetic detector that detects the sequence of photons that are focused from the focusing element(s). When the frequency selective electromagnetic detector senses a photon, the frequency selective electromagnetic detector emits an electrical pulse that has a voltage that is proportional to the energy level of the photon. Additionally, the system includes a processor that processes the electrical pulses, and de-multiplexes the sequence of emitted electrical pulses based on the electrical pulse voltage of the electrical pulses.

Abstract: An integrated proximity and ambient light sensor assembly includes an emitter of an IR proximity signal, and a detector configured to detect the IR proximity signal from the emitter when the apparatus is sensing proximity, and to detect ambient light when the apparatus is sensing ambient light. The assembly includes an IR cut filter that has a film disposed over the detector that rejects IR light but passes visible light to the detector, and an opening in the film centered over a midpoint of the detector that passes IR and visible light to the detector. The opening allows IR light to reach the detector from within a narrow angle, but absorbs undesirable emitted IR light that is reflected by oily build-up or “smudge” left on a cover of the device. The film allows visible light to pass for a wider angle to better determine average ambient light.

Abstract: A light sensor and light sensing system to detect an intensity of incident light and an angle of incidence of the incident light. The light sensor includes a dielectric layer, a plurality of photo detectors coupled relative to the dielectric layer, and a plurality of stacks of opaque slats embedded within the dielectric layer. The dielectric layer is substantially transparent to the incident light. The photo detectors detect the incident light through the dielectric layer. The stacks of opaque slats are approximately parallel to an interface between the dielectric layer and the photo detectors. The stacks of opaque slats define light apertures between adjacent stacks of opaque slats. At least some of the stacks of opaque slats are arranged at a non-zero angle relative to other stacks of the opaque slats.
