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 organic field effect transistor includes a channel structure having a photoalignment layer and an organic semiconductor layer disposed directly over the photoalignment layer, where a charge carrier mobility varies along a thickness direction of the channel structure. The channel structure may define an active area between a source and a drain of the transistor and may include alternating layers of at least two photoalignment layers and at least two organic semiconductor layers. Each photoalignment layer is configured to influence an orientation of molecules within an overlying organic semiconductor layer and hence impact the mobility of charge carriers within the device active area while also advantageously decreasing the OFF current of the device.

Abstract: A lightguide with partially reflective slanted polarization-selective bulk mirrors is disclosed. The lightguide may be used in a near-eye display with a polarized image source. The polarization-selective bulk mirrors reflect light of the polarized image source, and fully transmit light of the orthogonal polarization, causing the mirrors to be less conspicuous to an external viewer while preserving high efficiency of delivery of the image light to the viewer.

Abstract: A notched filter includes a multilayer having alternating first and second polymer layers, the first polymer layers each including an isotropic polymer thin film having in-plane refractive indices n1x and n1y, and the second polymer layers each including an isotropic or anisotropic polymer thin film having in-plane refractive indices n2x and n2y, where a thickness of each successive first polymer layer decreases with increasing distance from a centerline of the multilayer, and a thickness of each successive second polymer layer increases with increasing distance from the centerline. Such a filter may be configured to reflect incident light having a desired polarization state within a predetermined and relatively narrow band.

Abstract: A thermoplastic interposer formed of ordered polymer sheets that may be configured to act as an interconnect and as a thermal energy spreader. In examples, the thermoplastic interposer may include one or more extensions or wings to further dissipate heat. In examples, laser direct structuring (LDS) may be used to form or more through silicon vias (TSVs) or through-chip vias. In examples, the ordered polymer sheets may be extruded via a roll-to-roll process, stacked, and processed to form a laminate interposer structure that makes up the interposer. In examples, the thermoplastic interposer may be used in multi-layer structures interconnecting two or more board assemblies such as printed circuit boards (PCB)s.

Abstract: An example apparatus may include a display and an optical configuration configured to provide an image of a display, for example, in a head-mounted device. An example apparatus may include a display, a first lens assembly including a lens and a reflector, and a second lens assembly including a second lens and a second reflector. In some examples, the first lens assembly has a front surface configured to receive display light from the display when the display is energized. The first lens assembly may include a Fresnel surface (e.g., a Fresnel surface including facets and steps) that may, for example, be formed in a lens surface, or in the surface of a substrate supported by a lens surface. Other devices, methods, systems and computer-readable media are also disclosed.

Formation of the polymer thin film may include forming a polymer solution from a crystallizable polyethylene and a liquid solvent, forming a gel from the polymer solution, forming a polymer thin film from the gel by calendering or solid state extrusion, and stretching the polymer thin film.

Abstract: A polymer bilayer includes a layer of a porous fluoropolymer directly overlying a layer of polyethylene. The polyethylene layer may be porous or dense and may include an ultra-high molecular weight polymer. The polymer bilayer may be co-integrated with structures (e.g., wearable devices) exposed to high thermal loads (>0-1000 W/m2) and provide passive cooling thereof. For instance, passive cooling of AR/VR glasses under different solar loads may be achieved by a polymer bilayer that is both highly reflective across solar heating wavelengths and highly emissive in the long-wavelength infrared. The high reflectance decreases energy absorption across the solar spectrum while the high emissivity promotes radiative heat transfer to the surroundings.

Abstract: Examples include a device including a fluid lens having a membrane, a substrate, and a fluid at least partially enclosed between the membrane and the substrate. One or more support structures may be configured to provide a guide path for an edge portion of the membrane, which may be an elastic membrane in tension. In some examples, a membrane includes a membrane polymer, such as a thermoplastic urethane polymer, and a polymer additive, such as an acrylate polymer. The polymer additive may reduce or substantially eliminate diffusion of the fluid into the membrane, which may increase the stability and performance of the fluid lens.
