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: 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 transparent optical element may include a layer of an electroactive ceramic disposed between transparent electrodes, such that the electrodes are each oriented perpendicular to a non-polar direction of the ceramic layer. Optical properties of the optical element, including transmissivity, haze, and clarity may be improved by the application of a voltage to the electroactive ceramic, and an associated phase transformation.

Abstract: A device includes a pair of electrodes and a dynamic material disposed between the pair of electrodes, the dynamic material including a crystalline microstructure configured to change between at least two states in response to a change in an electric field between the two electrodes. A material includes tetragonal lead magnesium niobate-lead titanate (PMN-PT) and at least one lanthanide series element. A method includes doping a lead magnesium niobate-lead titanate material with at least one lanthanide series element, and processing the PMN-PT material to form tetragonal PMN-PT. A further method includes forming a low refractive index nanostructured grating over a carrier substrate, forming a high refractive index layer over the low refractive index grating to produce a nanostructured coupling element, forming an adhesive layer over the nanostructured coupling element, and affixing the nanostructured coupling element to a high index waveguide.

Abstract: Eye-tracking systems of the present disclosure may include at least one light source configured to emit modulated radiation toward an intended location for a user's eye. The modulated radiation may be modulated in a manner that enables the light source to be identified by detection and analysis of the modulated radiation. At least one optical sensor including at least one sensing element may be configured to detect at least a portion of the modulated radiation. A processor may be configured to identify, based on the modulated radiation detected by the optical sensor, the light source that emitted the modulated radiation. Various other methods, systems, and devices are also disclosed.

Abstract: An optical transformer includes a light source and an array of photovoltaic cells optically coupled to the light source, where at least a portion of the photovoltaic cells are connected in series. An optical connector such as a waveguide or an optical fiber may be disposed between an output of the light source and an input of the array of photovoltaic cells. Configured to generate a high voltage output, the optical transformer may be configured to power a device such as an actuator that provides a tunable displacement as a function of voltage.

Abstract: A liquid dispersion includes a matrix phase of polymerizable material and at least 10% by volume of solid conductive particles distributed throughout the matrix. The conductive particles may have an average particle size of less than approximately 100 nm, and the liquid dispersion may have a viscosity of less than approximately 100 Poise. Such a liquid dispersion may be printed or extruded and then cured to form a solid thin film. The content and distribution of conductive particles within the thin film may reach a percolation threshold such that the thin film may form a conductive layer. Polymer-based devices, such as nanovoided polymer (NVP)-based actuators may be formed by co-extrusion of a nanovoided polymer material between conductive polymer electrodes.
