Abstract: A method, includes providing a wafer including a first surface grating extending over a first area of a surface of the wafer and a second surface grating extending over a second area of the surface of the wafer; de-functionalizing a portion of the surface grating in at least one of the first surface grating area and the second surface grating area; and singulating an eyepiece from the wafer, the eyepiece including a portion of the first surface grating area and a portion of the second surface grating area. The first surface grating in the eyepiece corresponds to an input coupling grating for a head-mounted display and the second surface grating corresponds to a pupil expander grating for the head-mounted display.

Abstract: In some embodiments, a near-eye, near-eye display system comprises a stack of waveguides having pillars in a central, active portion of the waveguides. The active portion may include light outcoupling optical elements configured to outcouple image light from the waveguides towards the eye of a viewer. The pillars extend between and separate neighboring ones of the waveguides. The light outcoupling optical elements may include diffractive optical elements that are formed simultaneously with the pillars, for example, by imprinting or casting. The pillars are disposed on one or more major surfaces of each of the waveguides. The pillars may define a distance between two adjacent waveguides of the stack of waveguides. The pillars may be bonded to adjacent waveguides may be using one or more of the systems, methods, or devices herein. The bonding provides a high level of thermal stability to the waveguide stack, to resist deformation as temperatures change.

Abstract: In an example method for forming a variable optical viewing optics assembly (VOA) for a head mounted display, a prepolymer is deposited onto a substrate having a first optical element for the VOA. Further, a mold is applied to the prepolymer to conform the prepolymer to a curved surface of the mold on a first side of the prepolymer and to conform the prepolymer to a surface of the substrate on a second side of the prepolymer opposite the first side. Further, the prepolymer is exposed to actinic radiation sufficient to form a solid polymer from the prepolymer, such that the solid polymer forms an ophthalmic lens having a curved surface corresponding to the curved surface of the mold, and the substrate and the ophthalmic lens form an integrated optical component. The mold is released from the solid polymer, and the VOA is assembled using the integrated optical component.

Abstract: A head-mounted, near-eye display system comprises a stack of waveguides having integral spacers separating the waveguides. The waveguides may each include diffractive optical elements that are formed simultaneously with the spacers by imprinting or casting. The spacers are disposed on one or more major surfaces of the waveguides and define a distance between immediately adjacent waveguides. Adjacent waveguides may be bonded using adhesives on the spacers. The spacers may fit within indentations of overlying waveguides. In some cases, the spacers may form one or more walls of material substantially around a perimeter of an associated waveguide. Vent holes may be provided in the walls to allow gas flow into and out from an interior volume defined by the spacers. Debris trapping structures may be provided between two walls of spacers to trap and prevent debris from entering into the interior volume.

Abstract: Color-selective waveguides, methods for fabricating color-selective waveguides, and augmented reality (AR)/mixed reality (MR) applications including color-selective waveguides are described. The color-selective waveguides can advantageously reduce or block stray light entering a waveguide (e.g., red, green, or blue waveguide), thereby reducing or eliminating back-reflection or back-scattering into the eyepiece.
