Abstract: An eyepiece waveguide for an augmented reality display system includes a substrate having a first surface and a second surface and a diffractive input coupling element formed on or in the first surface or the second surface of the substrate. The diffractive input coupling element is configured to receive an input beam of light and to couple the input beam into the substrate as a guided beam. The eyepiece waveguide also includes a diffractive combined pupil expander-extractor (CPE) element formed on or in the first surface or the second surface of the substrate. The diffractive CPE element includes a first portion and a second portion divided by an axis. A first set of diffractive optical elements is disposed in the first portion and oriented at a positive angle with respect to the axis and a second set of diffractive optical elements is disposed in the second portion and oriented at a negative angle with respect to the axis.

Abstract: A method of fabricating a multi-element fiber scanner includes providing a fiber optic cable having a cladding region and a fiber core and focusing a laser beam at a series of predetermined locations inside the cladding region of the fiber optic cable. The method also includes creating a plurality of damage sites at the predetermined locations, exposing the fiber optic cable to an etchant solution, and preferentially etching the plurality of damage sites to form a base having a base plane and a longitudinal axis orthogonal to the base plane, a retention collar disposed a predetermined distance along the longitudinal axis from the base, a first fiber link including the fiber core, passing through the base plane, and joined to the retention collar, and a plurality of additional links joined to the base, extending from the base to the retention collar, and joined to the retention collar.

Abstract: An augmented reality display system includes a pair of variable focus lens elements that sandwich a waveguide stack. One of the lens elements is positioned between the waveguide stack and a user's eye to correct for refractive errors in the focusing of light projected from the waveguide stack to that eye. The lens elements may also be configured to provide appropriate optical power to place displayed virtual content on a desired depth plane. The other lens element is between the ambient environment and the waveguide stack, and is configured to provide optical power to compensate for aberrations in the transmission of ambient light through the waveguide stack and the lens element closest to the eye. In addition, an eye-tracking system monitors the vergence of the user's eyes and automatically and continuously adjusts the optical powers of the pair of lens elements based on the determined vergence of those eyes.

Abstract: A display subsystem for a virtual image generation system for use by an end user comprises a planar waveguide apparatus, an optical fiber, at least one light source configured for emitting light from a distal end of the optical fiber, and a collimation element mounted to a distal end of the optical fiber for collimating light from the optical fiber. The virtual image generation system further comprises a mechanical drive assembly to which the optical fiber is mounted to the drive assembly. The mechanical drive assembly is configured for displacing the distal end of the optical fiber, along with the collimation element, in accordance with a scan pattern. The virtual image generation system further comprises an optical waveguide input apparatus configured for directing the collimated light from the collimation element down the planar waveguide apparatus, such that the planar waveguide apparatus displays image frames to the end user.

Abstract: A waveguide apparatus includes a planar waveguide and at least one optical diffraction element (DOE) that provides a plurality of optical paths between an exterior and interior of the planar waveguide. A phase profile of the DOE may combine a linear diffraction grating with a circular lens, to shape a wave front and produce beams with desired focus. Waveguide apparati may be assembled to create multiple focal planes. The DOE may have a low diffraction efficiency, and planar waveguides may be transparent when viewed normally, allowing passage of light from an ambient environment (e.g., real world) useful in AR systems. Light may be returned for temporally sequentially passes through the planar waveguide. The DOE(s) may be fixed or may have dynamically adjustable characteristics. An optical coupler system may couple images to the waveguide apparatus from a projector, for instance a biaxially scanning cantilevered optical fiber tip.

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.
