An Evening with Meta Materials: Automated Lens Casting Embedding Multi-functional Metasurfaces for AR displays

Dr. Jonathan Waldern, CTO at Meta Materials

Meta Materials Inc. (MMAT) is developing discrete platform specific proprietary technologies for large-surface-area lithography, allowing the manufacture of nanostructures to be carried out in a cost-effective manner. Each platform employs a massively parallel patterning scheme, designed to be scalable to large areas of either rigid substrate materials and rolls of flexible films. In certain cases we use a phase-shift mask approach called Rolling Mask Lithography and in others, cast NIL printing – all allowing the creation of resonate plasmonic structures with feature sizes down to 50 nm. META’s ARfusion™ combines precision cast lens fabrication tools and functional metasurfaces, to provide AR wearable developers with a platform for seamlessly integrating these nanostructures into thin lightweight prescription glasses. These embedded technologies can include waveguides, microdisplays, holographic filters, polarizing, liquid crystal/electrochromic foils, antifogging and eyeglow suppression films, antennas, and eye trackers. The ARfusion™ platform enables scalable and versatile fabrication processes for manufacturing AR glasses of any size and shape in large volumes, providing a significant cost advantage over current methods.
