"We believe we can use technology to lean into the ‘reality’ of augmented reality — encouraging everyone, ourselves included, to stand up, walk outside, and connect with people and the world around us. This is what we humans are born to do, the result of two million years of human evolution, and as a result those are the things that make us the happiest. Technology should be used to make these core human experiences better — not to replace them." .

US20250291100 - OPTICAL MATERIAL ENCAPSULATED DIFFRACTIVE GRATINGS []...]F Due to the sets of grating structures of a lightguide directing light based on the parameters of the grating structures, changing how a set of grating structures directs light requires modifying one or more parameters of the grating structures. However, modifying the parameters of the grating structures requires fabricating a new set of grating structures with the modified parameters.[...] As such, modifying the parameters of the grating structures to compensate for manufacturing tolerances, manufacturing errors, design changes, and the like requires new sets of grating structures to be fabricated, increasing the cost and time needed to manufacture lightguides including these sets of grating structures. While fabricating a lightguide including such sets of diffractive grating structures, certain conditions arise requiring how a set of diffractive grating structures directs light to be modified (e.g., requiring the diffraction efficiency of the set of diffractive grating structures to be modified). For example, in response to certain tolerances in the manufacturing process of a lightguide, one or more components of a lightguide (e.g., incoupler, EPE, outcoupler, body) deviate from a desired function (e.g., one or more components of the lightguide disperse light differently than intended). To compensate for these deviations, the diffraction efficiencies of one or more sets of diffractive grating structures are modified such that the lightguide functions as intended. As another example, certain characteristics or parameters for a set of diffractive grating structures increase the chance of introducing deformities in one or more components of the lightguide during the manufacturing processes such as air bubbles, working stamp damage, or the like. Such deformities in the components of the lightguide prevent these components from operating as intended. To compensate for these deformities, the diffraction efficiencies at which one or more sets of diffractive grating structures direct light are modified such that the lightguide operates as desired. However, because a set of diffractive grating structures is configured to direct light based on the physical parameters (e.g., angle, depth, period) of the diffractive grating structures in the set of diffractive grating structures, modifying how a set of diffractive gratings directs light (e.g., modifying the diffraction efficiency) requires changing one or more parameters of the diffractive grating structures. To change these physical parameters, the diffractive grating structures must be refabricated with the modified parameters, which increases the time and cost required to fabricate the lightguide. To this end, systems and techniques disclosed herein are directed to a lightguide including a deposited optical material configured to modify how a set of diffractive grating structures directs received light (e.g., to modify the diffraction efficiency at which a set of diffractive grating structures directs received light). For example, such a lightguide includes a substrate having opposing surfaces that is formed from an effectively transparent material so as to allow a user to view a real-world space in front of the user. Deposed on a first surface of this substrate is a set of diffractive grating structures having one or more predetermined parameters based on a pattern of a master stamp, such as predetermined angles, predetermined duty cycles, predetermined periods, predetermined heights, and the like. Additionally, the lightguide includes an optical material deposited on the first surface of the substrate such that one or more diffractive grating structures of the set of diffractive grating structures are at least partially encapsulated by the optical material. Such an optical material, for example, has a predetermined refractive index that causes a fraction of the light received by the optical material to be diffracted at an angle based on the predetermined refractive index. As an example, the optical material includes a refractive index that causes a fraction of light received by the optical material to be directed toward the set of diffractive grating structures, a surface of the lightguide, or both such that the fraction of light is incident upon a surface of the lightguide, the diffractive grating structures of the set of diffractive grating structures, or both at a predetermined angle. The surfaces of the lightguide, the set of diffractive grating structures, or both then direct the received fraction of light based on one or more parameters of the diffractive grating structures, the predetermined angle upon which the received light is incident, or both. In this way, a lightguide allows how a set of diffractive grating structures directs light to be modified without changing the physical parameters of the diffractive grating structures. That is to say, the lightguide allows for the diffractive index of a set of diffractive gratings to be modified without changing the physical parameters of the diffractive grating structures.

Full-colour 3D holographic augmented-reality displays with metasurface waveguides
Emerging spatial computing systems seamlessly superimpose digital information on the physical environment observed by a user, enabling transformative experiences across various domains, such as entertainment, education, communication and training1–3. However, the widespread adoption of augmented-reality (AR) displays has been limited due to the bulky projection optics of their light engines and their inability to accurately portray three-dimensional (3D) depth cues for virtual content, among other factors4,5. Here we introduce a holographic AR system that overcomes these challenges using a unique combination of inverse-designed full-colour metasurface gratings, a compact dispersion-compensating waveguide geometry and artificial-intelligence-driven holography algorithms. These elements are co-designed to eliminate the need for bulky collimation optics between the spatial light modulator and the waveguide and to present vibrant, full-colour, 3D AR content in a compact device form factor. To deliver unprecedented visual quality with our prototype, we develop an innovative image formation model that combines a physically accurate waveguide model with learned components that are automatically calibrated using camera feedback. Our unique co-design of a nanophotonic metasurface waveguide and artificial-intelligence-driven holographic algorithms represents a significant advancement in creating visually compelling 3D AR experiences in a compact wearable device. We develop a method for providing high-quality, holographic, three-dimensional augmented-reality images in a small form factor suitable for incorporation in eyeglass-scale wearables, using high-refraction-index glass waveguides with nanoscale metasurfaces, and incorporating artificial intelligence.

This is not that novel principle on smartglasses, implemented, for example, with liquid crystals or the like. Other companies proposed versions of the mechanism in the past. What is novel is the implementation by Meta, up to now and the possible novel algorithms to drive the pixellated area layer

"The multi-state scattering panels can be selectively activated based on a trigger, such as identification of an object in the real-world environment, based on an event occurring in an XR application executing on the XR display, based on detected audio, etc."
Aspects of the present disclosure integrate pixelated multi-state panels (e.g., liquid crystal dimming panels) into artificial reality (XR) displays (e.g., augmented reality (AR) glasses) or conventional glasses. Conventional visual displays for XR displays can be expensive, have a low field-of-view, and consume high power. On the other hand, pixelated multi-state panels consume lower power, have a wide field-of-view, and are light, inexpensive, and computationally simple. The multi-state panels can have 4 configurations: 1) included on the periphery of an XR display, 2) as a standalone display, 3) as a display that's overlaid onto an XR display, and/or 4) as a secondary externally facing display. The multi-state panels can be selectively activated based on a trigger, such as identification of an object in the real-world environment, based on an event occurring in an XR application executing on the XR display, based on detected audio, etc.
