Abstract

Glass diffractive waveguides have gained significant importance in Augmented Reality (AR) near-eye display designs as they currently offer the best tradeoff between form factor and field-of-view. In this talk, we will discuss our continuous efforts to provide the best glass substrates that enable both wider field-of-view and thinner, lighter, and brighter devices. The impact of smaller image source exit pupils on glass waveguide designs will be discussed as the industry is driving toward further shrinkage of the optical engine. Both optical glass materials and substrate geometry will be discussed in relation to the expected display performances. We will introduce the latest generation of Corning glass substrates for AR and our current product roadm
