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

Abstract: A polymer thin film includes polyethylene having a weight average molecular weight of at least approximately 500,000 g/mol, where the thin film is characterized by transparency within the visible spectrum of at least approximately 80%, bulk haze of less than approximately 5%, and an in-plane elastic modulus of at least approximately 10 GPa. The polymer thin film may be thermally conductive and may be incorporated into an optical element and configured to dissipate heat, such as from a light-emitting device.

Abstract: A polymer article includes an at least partially disentangled polyvinylidene fluoride (PVDF) family member composition and is characterized by an elastic modulus of at least 4 GPa and an electromechanical coupling factor (k31) of at least 0.1 at room temperature. A method of manufacturing such a polymer article may include forming an at least partially disentangled polymer composition into a polymer thin film or fiber, applying a tensile stress to the polymer article in an amount effective to induce a stretch ratio of at least approximately 5 in the thin film or fiber, and applying an electric field across a thickness dimension of the polymer article. Annealing and poling steps may separately or simultaneously accompany and/or follow the act of stretching.

Abstract: A lighting assembly may include a light source and a reflective polarizer overlapping the light source. A portion of light that is incident on the reflective polarizer may not pass through the reflective polarizer and may be reflected back to the light source. The light source may include at least one of a light emitting diode (LED), a micro-LED, an organic light emitting diode (OLED), a micro-OLED, a liquid crystal on silicon (LCoS), or an fLCoS light source. The reflective polarizer may include a polymer birefringent multilayer structure of alternating first layers and second layers. The first layers may each include an isotropic polymer thin film the second layers each include an anisotropic polymer thin film. Various other devices, systems, and methods are also disclosed.

Abstract: An actuator assembly includes a primary electrode, a secondary electrode overlapping at least a portion of the primary electrode, and an electroactive polymer layer disposed between the primary electrode and the secondary electrode, where the electroactive polymer layer includes a non-vertical (e.g., sloped) sidewall with respect to a major surface of at least one of the electrodes. The electroactive polymer layer may be characterized by a non-axisymmetric shape with respect to an axis that is oriented orthogonal to an electrode major surface.

Abstract: A multilayer polymer thin film includes an anti-reflective coating directly overlying a reflective polarizer stack. The reflective polarizer stack includes alternating first and second polymer layers, where the first layers include an isotropic polymer thin film and the second layers include an anisotropic polymer thin film. The anti-reflective coating (ARC) includes alternating third and fourth layers, where the third layers include an isotropic polymer thin film or an anisotropic polymer thin film and the fourth layers include an isotropic polymer thin film. The multilayer polymer thin film may be formed by co-extrusion where the reflective polarizer stack and the anti-reflective coating are formed simultaneously.

Abstract: A method includes applying a stress to a polymer thin film to stretch the polymer thin film along a first in-plane direction, and subsequently applying a stress to the polymer thin film to stretch the polymer thin film along a second in-plane direction orthogonal to the first in-plane direction to form an ultra-high modulus polymer thin film. Calendaring or hot pressing of the ultra-high modulus polymer thin film may improve its optical and/or thermal properties.
