Abstract: A method of forming a high voltage optical transformer includes forming a via through a transparent carrier wafer, forming a conductive layer within the via, bonding a solid state lighting (SSL) package to a first side of the carrier wafer, and bonding a photovoltaic (PV) wafer to a second side of the carrier wafer opposite to the first side. The photovoltaic wafer may include an active area and a conductive area located outside of the active area that is in electrical contact with the conductive layer. The method further includes forming both an SSL contact with the solid state lighting package and a PV contact with the conductive layer on the same side of the carrier wafer.

Abstract: An example apparatus may include a display, a beamsplitter having a first region and a second region, and a reflective polarizer. The reflectance of the second region of the beamsplitter may be appreciably greater than the reflectance of the first region; for example, at least approximately 20% greater. In some examples, the second region may be a peripheral region surrounding a generally centrally located first region. An example apparatus may be configured so that at least some light emitted by the display is transmitted through the first region of the beamsplitter, reflects from the reflective polarizer, reflects from the second region of the beamsplitter, and is then directed through the reflective polarizer to an eye of a user when the user wears the apparatus. Other devices, methods, systems, and computer-readable media are also disclosed.

Abstract: An optically or mechanically anisotropic polymer thin film is characterized by compound curvature, where a maximum variation of an angle of orientation of an extraordinary axis of the polymer thin film is at most 2% greater than an orientation variation associated with an initially planar polymer thin film formed to the same compound curvature.

Abstract: An optical element (e.g., a lens) may include an optically uniaxial or optically biaxial organic solid, for example, an organic molecular solid. The direction of a maximum refractive index of the organic solid may be aligned substantially orthogonal to an optical axis of the lens. In some examples, a device may include a display and an optical configuration configured to receive light from the display and direct the light to a remote view location. In some examples, the optical configuration may comprise a lens and at least one surface of the lens may include a plurality of facets, for example, to form a Fresnel lens.

CPC classification number: G02B3/14
Abstract: A liquid lens includes a substrate, a transparent elastic membrane forming a cavity with the substrate, and a transparent fluid filling the cavity between the substrate and the membrane. The membrane has a pre-distorted, rotationally asymmetric shape in absence of the fluid in the cavity. When the cavity is filled with the fluid and the substrate is disposed vertically w.r.t. gravity at a pre-defined clocking angle, the membrane adopts a substantially rotationally symmetric shape due to elasticity of the membrane counteracting gravity exerting a downward force on the fluid in the cavity, reducing the effect of the gravity sag on optical performance of the liquid lens.

Abstract: An optically clear, high strength, high modulus, and high thermal conductivity polyethylene thin film may be formed from a crystallizable polymer and an additive configured to interact with the crystallizable polymer to facilitate crystallite alignment and, in some examples, create a higher crystalline content within the polyethylene thin film. The polyethylene thin film may be characterized by a bimodal molecular weight distribution where the molecular weight of the additive may be less than approximately 5% of the molecular weight of the crystallizable polymer. Example crystallizable polymers may include high molecular weight polyethylene, high density polyethylene, and ultra-high molecular weight polyethylene. Example additives may include low molecular weight polyethylene and polyethylene oligomers. The polyethylene thin film may be characterized by a Young's modulus of at least approximately 10 GPa, a tensile strength of at least approximately 0.7 GPa, and a thermal conductivity of at least approximately 5 W/mK.

Abstract: A fluidic optical element includes a bilayer having a fluid layer and a gel layer directly overlying the fluid layer, and a primary electrode disposed over a surface of the bilayer. The geometry of an interface between the fluid layer and the gel layer and hence the optical response of the bilayer to incident light may be manipulated using the principle of dielectrophoresis.
