Abstract: Configurations for a beam deflector metasurface are disclosed. The beam deflector metasurface may include beam deflectors arranged in a repeating, radial pattern of concentric zones. The beam deflector metasurface may be a large area, high numerical aperture metasurface optic with high efficiency when directing light at non-normal angles of incidence. The different concentric zones may direct received light in varying directions with various steepness of angles. The beam deflectors may include pillars that may be the same or different width, height, or shape. The pillars may function as diffractive gratings and the cross-coupling between the pillars may direct the output light. The zones of the beam deflector metasurface may allow for diffusing hot spots and spreading the light evenly over the target area. The beam deflector metasurface may be used for non-imaging applications where the deterioration of focus allows for better efficiency at non-normal input and output angles of incidence. The beam deflectors may be designed for polarization and wavelength sensitivity as well as allowing for multiple processing benefits such as patterning the beam deflectors onto active devices.

Abstract: An electronic device such as a head-mounted device may have a display that displays computer-generated content for a user. The head-mounted device may have an optical system that directs the computer-generated content towards eye boxes for viewing by a user. The optical system may include a spatially addressable adjustable optical component. The adjustable optical component may have first and second electrodes and an electrically adjustable material between the first and second electrodes. The electrically adjustable material may include a transparent conductive material such as indium tin oxide that includes a pattern of segmented trenches configured to provide the transparent conductive material with electrical anisotropy. Contacts may be coupled to the transparent conductive material. Control circuitry can adjust the electrically adjustable material to form a spatially addressable light modulator or adjustable lens.

Abstract: A display system may include a waveguide with an output coupler that couples image light out of the waveguide and towards an eye box. The output coupler may also transmit world light from real-world objects towards the eye box. A bias lens may pass the world light to the output coupler. An adjustable tint layer having multiple states that involve transmission of different amounts of the world light may be disposed between the bias lens and the output coupler. Different states may impart different colors and/or may impart a gradient transmission characteristic to the world light. The bias lens itself may form the adjustable tint layer. The adjustable tint layer may have a transparent electrode layer that is provided with one or more AC voltages that heat the adjustable tint layer. The adjustable tint layer may be a self-switching electrochromic device that includes a transparent solar cell.
