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 element located at the input end for coupling light into the waveguide body, and an output coupling element located at the output end for coupling light out of the waveguide body, where the waveguide body includes an organic solid crystal. The organic solid crystal may be a single crystal having principal axes rotated with respect to the dimensions of the waveguide body. Such an optical element may have low weight and exhibit good color uniformity while providing polarization scrambling of the guided light.

Abstract: A lens system may include a lens having a liquid crystal layer and a driving electrode array disposed on a first side of the liquid crystal layer, the driving electrode array including a plurality of driving zones that are independently operable. The plurality of driving zones may each include a plurality of driving electrodes consecutively arranged along a radial direction extending from a central region of the lens. The lens system may include a controller that is configured to independently operate each of the plurality of driving zones via a separate plurality of bus lines coupled to each of the plurality of driving zones. The controller may be configured to operate at least one of the driving zones based on a gaze direction of the user. Various other devices, systems, and methods are also disclosed.
