Abstract: An output device of an event indicator system is mounted relative to a surface such as a wall, a ceiling, or a floor. The output device includes a housing configured to mount to the wall or the ceiling. The housing includes a cavity. A movable door is coupled to the housing and is configured to transition between an open position and a closed position. A laser is positioned within the cavity and configured to project a graphic onto the surface when the movable door is in the open position. The laser is inoperable to project the graphic onto the surface when the movable door is in the closed position.

Abstract: A headlamp assembly is provided that includes a circuit board that is attached to the bottom of a headlamp reflector and that includes a plurality of light emitting elements. The plurality of light emitting elements are arranged on the circuit board in a high-beam and low-beam producing pattern configured to generate light toward the outer edge of the headlamp reflector. The headlamp assembly also includes an optical lens that includes a first optical surface and a second optical surface. The optical lens optically forms a low-beam light pattern and a high-beam light pattern from the light generated from the plurality of light emitting elements through the optical lens.

Abstract: A dynamic segmented-reflector for a vehicle headlamp that includes a light source and a substrate formed as a reflector sidewall. The reflector sidewall includes reflector facets that are grown on the reflector sidewall. The reflector facets include at least one mirrored surface that faces the light source, and the reflector facets are configured to adjust position to form different light patterns.

Abstract: A hollow-core waveguide structure for guiding an electromagnetic signal, comprising: a core material comprising a predetermined refractive index; and a cladding structure disposed about the core material, wherein the cladding structure has a refractive index that is less than unity; wherein the cladding structure comprises an Epsilon-near-zero (ENZ) metamaterial. The core material comprises air or the like. The cladding structure comprises one of substantially planar sheets disposed about the core material and a substantially tubular structure disposed about the core material. Optionally, the ENZ metamaterial comprises a plurality of nanostructures disposed in a host medium. The plurality of nanostructures comprise a transparent conducting oxide. Alternatively, the cladding structure is manufactured via a self-assembly method.

Abstract: A metamaterial-based dispersion compensator includes a plurality of layers arranged in a geometric structure; wherein the plurality of layers comprise engineered metamaterials; wherein the engineered metamaterials and the geometric structure are configured to compensate dispersion across a wavelength spectrum. The metamaterial-based dispersion compensator utilizes a specifically engineered frequency response, in a compact metamaterial form-factor, to correct for naturally occurring and problematic dispersion in physical systems such as in optical communication systems.

Abstract: The present disclosure explores and fabricates coupled plasmonic nanoparticles of gold (Au), silver (Ag), or aluminum (Al) onto nanorods or nanowires of zinc telluride (ZnTe), silicon (Si), germanium (Ge), or other semiconductor materials. Full-wave simulation is performed to obtain an optimum design for maximum light absorption. The nanorods, after being coated with a shell to form a p-n junction, or being imparted with a radial junction, are of interest for enhanced light harvesting in solar cells, for example. The fabrication method of such arrays is described. Modeling of the spectral properties using equivalent circuit theory is implemented to predict fabrication results and provide an intuitive approach regarding the design of these optical metamaterials with predetermined properties.
