3.1 - Invited Paper: Reality vs. Simulations in Diffractive Waveguide Combiners (11:10 AM - 11:30 AM)

The researchers have developed an advanced design toolset capable of optimizing image quality and performance of augmented-reality near-eye and head-up displays based on diffractive waveguide technology. This can accurately simulate the operation of nano-scale diffractive surface-relief gratings in an optical waveguide with macro-scale dimensions. They compare simulation results of key performance metrics to data measured from samples manufactured by state-of-the-art nanofabrication tools.
3.2 - Invited Paper: Current Technologies and Developments of AR Optics (11:30 AM - 11:50 AM)

This paper introduces two of the most widely used optic structures for AR glasses; waveguide and birdbath structures, plus one additional optic structure that has the advantages of the two former structures.
3.3 - Anamorphic-XR: Imaging Waveguide Technology for Efficient and Wide Field-of-View Near-Eye Display (11:50 AM - 12:10 PM)

A near-eye display technology incorporating novel imaging waveguides is described. Simulations and measurements indicate an achievable specification of 90º field-of-view at 60 ppd; >20% luminous efficiency; 80% polarized light transmission; and 10mm eyebox at 20mm eye relief from a 4mm thick waveguide. A hybrid immersive display is proposed, combining an anamorphic waveguide with a conventional VR display.

A curved waveguide for near-eye display is proposed. Two conditions for image transfer through curved waveguide are defined. These conditions have been satisfied using a compensator and grating with a law of variation of the grating period and verified by prototyping eyeglasses with 150mm radius of curvature of the waveguide with thickness of 2 mm, providing full color, 30-degree field of view, and 12 x 10mm eye box.
3.5 - Distinguished Student Paper: Full-Color, Wide FoV Single-Layer Waveguide for AR Displays (12:30 PM - 12:50 PM)

The authors analyze the field-of-view (FoV) limitations in a single-layer, full-color waveguide-based augmented-reality display, revealing key influences from the waveguide's refractive index, exit pupil expansion (EPE) scheme, and combiner's angular response. Based on these analyses, they propose an optimized butterfly EPE scheme with gradient-pitch polarization volume gratings (PVGs), achieving a theoretical diagonal FoV of 54.06° with a 16:10 aspect ratio.
