Abstract: A polymer multilayer includes two or more laminated layers of ultra-drawn, ultra-high molecular weight polyethylene or high density polyethylene. A transparent laminated structure may include such a polymer multilayer disposed between a pair of transparent substrates. The polymer multilayer may be configured to induce a compressive stress in a near surface region of each transparent substrate, which may improve the toughness and fracture resistance of the laminated structure. A photothermal dye may be incorporated into the polymer matrix and the compressive stresses may be achieved using photothermal actuation of the dye-containing polyethylene layers.

Abstract: Techniques disclosed herein relate generally to eye-tracking in near-eye display systems. One example of an eye illuminator for eye-tracking includes a substrate transparent to visible light, an array of light sources immersed in the substrate and configured to emit infrared light, and a holographic optical element conformally coupled to a surface of the substrate and encapsulated by an encapsulation layer. The holographic optical element is configured to transmit the visible light and diffract the infrared light emitted by the array of light sources to the eye of a user for eye-tracking.

Abstract: A plurality of light sources such as vertical-cavity surface-emitting lasers (VCSELs) are configured to emit light through emission apertures. The light may be near-infrared light. Optics are formed over the emission apertures of the plurality of light sources. The optics may provide different tilt angles or divergence angles to the non-visible light emitted by the light sources in the plurality of light sources.
