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.

Abstract: A polymer thin film includes polyethylene having a molecular weight of at least approximately 250,000 g/mol, and has an elastic modulus of at least approximately 25 GPa, a tensile strength of at least approximately 0.8 GPa, and a thermal conductivity of at least approximately 5 W/mK. 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.

Abstract: A light-emitting device includes a light-emitting diode having an emissive surface, and a capping layer including an organic solid crystal overlying the emissive surface. The refractive index of the organic solid crystal may be tuned such as through the application of a voltage, current, or stress to improve the light extraction efficiency of the device.

Abstract: A MEMS-based vertical cavity surface emitting laser (VCSEL) includes an embedded photodiode. A representative VCSEL includes a distributed Bragg reflector (DBR), a photodiode structure located within the distributed Bragg reflector, an active region overlying the distributed Bragg reflector, and a MEMS upper reflector disposed over the active region. The VCSEL may be configured as an optical sensor. The laser cavity and hence a working wavelength of the sensor may be tuned by modulating the MEMS reflector such as through an applied voltage.

Abstract: An optical element includes a waveguide body that is configured to guide light by total internal reflection from an input end to an output end, an input coupling structure located at the input end for coupling light into the waveguide body, and an output coupling structure located at the output end for coupling light out of the waveguide body, where the waveguide body includes a layer of an optically anisotropic organic solid crystal. Such an optical element may have low weight and exhibit good color uniformity while presenting a 2D diagonal field-of-view of at least approximately 10°.
