Abstract: Methods of manufacturing a liquid crystal device including depositing a layer of liquid crystal material on a substrate and imprinting a pattern on the layer of liquid crystal material using an imprint template are disclosed. The liquid crystal material can be jet deposited. The imprint template can include surface relief features, Pancharatnam-Berry Phase Effect (PBPE) structures or diffractive structures. The liquid crystal device manufactured by the methods described herein can be used to manipulate light, such as for beam steering, wavefront shaping, separating wavelengths and/or polarizations, and combining different wavelengths and/or polarizations.

Abstract: A method of manufacturing a waveguide having a combination of a binary grating structure and a blazed grating structure includes cutting a substrate off-axis, depositing a first layer on the substrate, and depositing a resist layer on the first layer. The resist layer includes a pattern. The method also includes etching the first layer in the pattern using the resist layer as a mask. The pattern includes a first region and a second region. The method further includes creating the binary grating structure in the substrate in the second region and creating the blazed grating structure in the substrate in the first region.

Abstract: A display device includes a waveguide assembly comprising a waveguide configured to outcouple light out of a major surface of the waveguide to form an image in the eyes of a user. An adaptive lens assembly has a major surface facing the output surface and a waveplate lens and a switchable waveplate assembly. The switchable waveplate assembly includes quarter-wave plates on opposing sides of a switchable liquid crystal layer, and electrodes on the quarter-wave plates in the volume between the quarter-wave plates. The electrodes can selectively establish an electric field and may serve as an alignment structure for molecules of the liquid crystal layer. Portions of the adaptive lens assembly may be manufactured by roll-to-roll processing in which a substrate roll is unwound, and alignment layers and liquid crystal layers are formed on the substrate as it moves towards a second roller, to be wound on that second roller.

Abstract: Architectures are provided for selectively incoupling one or more streams of light from a multiplexed light stream into a waveguide. The multiplexed light stream can have light with different characteristics (e.g., different wavelengths and/or different polarizations). The waveguide can comprise in-coupling elements that can selectively couple one or more streams of light from the multiplexed light stream into the waveguide while transmitting one or more other streams of light from the multiplexed light stream.

Abstract: Systems, apparatus, and methods for double-sided imprinting are provided. An example system includes first rollers for moving a first web including a first template having a first imprinting feature, second rollers for moving a second web including a second template having a second imprinting feature, dispensers for dispensing resist, a locating system for locating reference marks on the first and second webs for aligning the first and second templates, a light source for curing the resist, such that a cured first resist has a first imprinted feature corresponding to the first imprinting feature on one side of the substrate and a cured second resist has a second imprinted feature corresponding to the second imprinting feature on the other side of the substrate, and a moving system for feeding in the substrate between the first and second templates and unloading the double-imprinted substrate from the first and second webs.

Abstract: Very high refractive index (n>2.2) lightguide substrates enable the production of 70° field of view eyepieces with all three color primaries in a single eyepiece layer. Disclosed herein are viewing optics assembly architectures that make use of such eyepieces to reduce size and cost, simplifying manufacturing and assembly, and better-accommodating novel microdisplay designs.
