摘要： A method of forming a nanovoided composite polymer includes forming a resin-containing layer over a substrate, the resin-containing layer including a polymer-forming phase and a sacrificial phase, curing the polymer-forming phase to form a polymer matrix containing the sacrificial phase, and removing the sacrificial phase selectively with respect to the polymer matrix to form a nanovoided composite polymer including the polymer matrix and nanovoids dispersed throughout the polymer matrix. The nanovoids may be randomly or regularly dispersed throughout the matrix. Various other methods, systems, apparatuses, and materials are also disclosed.

摘要： A polymer layer includes a first in-plane refractive index extending along a first direction of the polymer layer, a second in-plane refractive index less than the first in-plane refractive index extending along a second direction of the polymer layer orthogonal to the first direction, a third refractive index along a direction orthogonal to both the first direction and the second direction, and a plurality of wrinkles extending along a surface of the polymer layer, where a difference between the first in-plane refractive index and the second in-plane refractive index is at least approximately 0.05, and the third refractive index is greater than the second in-plane refractive index.

摘要： 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.

摘要： A form birefringent optical element includes a structured layer and a dielectric environment disposed over the structured layer. At least one of the structured layer and the dielectric environment includes a nanovoided polymer, the nanovoided polymer having a first refractive index in an unactuated state and a second refractive index different than the first refractive index in an actuated state. Actuation of the nanovoided polymer can be used to reversibly control the form birefringence of the optical element. Various other apparatuses, systems, materials, and methods are also disclosed.

摘要： A polymer thin film is characterized by a first in-plane refractive index (nx) along a first direction of the polymer thin film, a second in-plane refractive index (ny) along a second direction of the polymer thin film orthogonal to the first direction, and a third refractive index (nz) along a thickness direction substantially orthogonal to both the first direction and the second direction, where nx>nz>ny. Such a polymer thin film may exhibit one or more of (a) an in-plane birefringence of at least approximately 0.05, and (b) nx greater than approximately 1.7.

摘要： An optical element includes a nanovoided polymer layer having a first refractive index in an unactuated state and a second refractive index different than the first refractive index in an actuated state. Compression or expansion of the nanovoided polymer layer, for instance, can be used to reversibly control the size and shape of the nanovoids within the polymer layer and hence tune its refractive index over a range of values, e.g., during operation of the optical element. Various other apparatuses, systems, materials, and methods are also disclosed.

摘要： A light-emitting disclosure (LED) and an LED array are disclosed. The LED includes a semiconductor junction for emitting light and an optical surface coupled to the semiconductor junction for outputting at least a portion of the light. The optical surface can include a grating structure configured to increase the portion of the light outputted by the optical surface, and/or a redirecting structure configured to redirect the portion of the light to form an output optical beam.

摘要： A directional illuminator for a display apparatus includes a switchable diffuser for tuning a divergence of a light beam illuminating a display panel of the display apparatus. The tunable divergence of the illuminating light beam translates into a tunable exit pupil size at the eyebox of the display apparatus, which may be matched to a pupil size of a user’s eye, thus providing a configurable illumination of the eye pupil. A tiltable reflector in an optical path of the illuminating light beam may be used to shift the location of the exit pupil at the eyebox of the display apparatus.
