Building High Performance, Scalable Waveguide Combiners

Magic Leap’s vertically integrated waveguide combiner production solution has enabled a revolutionary AR display, scaled with high yield and low cost. This presentation will examine the strategy and key capabilities needed to manufacture large field of view diffractive waveguide combiners with high efficiency, contrast, sharpness, and color uniformity. Magic Leap’s team of optical designers and process engineers have continuously redefined design rules and evolved diffractive waveguide designs with proprietary diffractive waveguide design tools in combination with proprietary Jet and Flash Imprint Lithography (J-FIL) Technology based on custom formulated, in-house imprint resist, low-cost sub-masters, and custom high-precision equipment. Precision engineers designing custom equipment, in collaboration with a team of process engineers utilizing statistical process techniques, deliver robust process capability, low-cost process solutions that cannot be sourced anywhere else in the world. To ensure consistent high-volume production, Magic Leap relies on our deep understanding of the correlation between optical and process performance measured through rigorously designed optical test equipment running custom algorithms. This vertical integration from design to high-volume manufacturing allows us to deliver high-performance, low-cost waveguide combiners on a rapid timeline.
