Abstract: An optical device comprising may include a wedge-shaped light turning element. The optical device can include a first surface that is parallel to a horizontal axis and a second surface opposite to the first surface that is inclined with respect to the horizontal axis by a wedge angle. The optical device may include a light module that includes a plurality of light emitters. The light module can be configured to combine light for the plurality of emitters. The optical device can further include a light input surface that is between the first and the second surfaces and is disposed with respect to the light module to receive light emitted from the plurality of emitters. The optical device may include an end reflector that is disposed on a side opposite the light input surface. The second surface may be inclined such that a height of the light input surface is less than a height of the side opposite the light input surface. The light coupled into the wedge-shaped light turning element may be reflected by the end reflector and/or reflected from the second surface towards the first surface.

Abstract: Methods and systems for depth-based foveated rendering in the display system are disclosed. The display system may be an augmented reality display system configured to provide virtual content on a plurality of depth planes using different wavefront divergence. Some embodiments include monitoring eye orientations of a user of a display system based on detected sensor information. A fixation point is determined based on the eye orientations, the fixation point representing a three-dimensional location with respect to a field of view. Location information of virtual objects to present is obtained, with the location information indicating three-dimensional positions of the virtual objects. Resolutions of at least one virtual object is adjusted based on a proximity of the at least one virtual object to the fixation point. The virtual objects are presented to a user by display system with the at least one virtual object being rendered according to the adjusted resolution.

Abstract: A two-dimensional waveguide light multiplexer is described herein that can efficiently multiplex and distribute a light signal in two dimensions. An example of a two-dimensional waveguide light multiplexer can include a waveguide, a first diffraction grating, and a second diffraction grating disposed above the first diffraction grating and arranged such that the grating direction of the first diffraction grating is perpendicular to the grating direction of the second diffraction grating. Methods of fabricating a two-dimensional waveguide light multiplexer are also disclosed.

Abstract: An optical device includes a liquid crystal layer having a first plurality of liquid crystal molecules arranged in a first pattern and a second plurality of liquid crystal molecules arranged in a second pattern. The first and the second pattern are separated from each other by a distance of about 20 nm and about 100 nm along a longitudinal or a transverse axis of the liquid crystal layer. The first and the second plurality of liquid crystal molecules are configured as first and second grating structures that can redirect light of visible or infrared wavelengths.
