The need for remote working technologies driven by the pandemic and the popularity of virtual reality devices is driving a broad interest in augmented reality (AR) devices for enterprise as well as consumer applications. AR devices consist of three key components to deliver a superior augmented experience to users. Waveguides is one of the key components that capture the image/light from the display engine to deliver digital images as well as real world images to user's eyes. This presentation will discuss how TOK is leveraging its core competencies in designing, engineering, and high volume manufacturing of high purity optical materials for semiconductor manufacturing, to develop novel optical materials that enable creation of structured surfaces for diffractive and meta optical elements for XR devices. We have developed high refractive index, low refractive index, and gap fill/planarization materials that can be applied using several technologies such as spin coating and ink-jet for replication technologies like lithography, nanoimprint lithography to enable AR/XR devices and emerging metaverse.
