End users’ expectation to smartglasses is benchmarked by today’s close-to-perfect displays in smartphones and the fashionable wearability of smartwatches with all-day battery power. The industry’s ambition to make an AR device part of everybody’s daily life requires uncompromising optical technologies. The architecture of choice promising to deliver this north star performance are waveguides. The material of choice to deliver the required performance of glass. Within the waveguide family, different light management technologies are considered: (a) diffractive structures (surface relief gratings or volume holographic gratings) manufactured by nano-photonic technologies or (b) reflective- geometric waveguides manufactured by conventional optical technologies with high requirements on tolerances. Driven by the commitment to define the industry’s reference of waveguide materials and components, we present our progress on SCHOTT’s two product lines: (1) SCHOTT RealView® high index glass wafers with progress in geometrical wafer quality, material innovation and coating technologies. (2) SCHOTT’s reflective waveguides, co-created in partnership with Israelian company Lumus, where the presentation will focus on manufacturing aspects of our new system architectures satisfying system design requirements of the industry.
