Optical components for waveguides – progress in high refractive index glass wafers for diffractives architectures and manufacturing aspects of reflective waveguides
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.

Benefits of high refractive index inkjet nanoimprint and light absorbing materials in creation of XR waveguide devices
This presentation explains the key benefits of inkjet coated high index of refraction nanoimprint materials and high index of refraction light absorbing black materials in XR waveguide manufacturing. With the inkjet nanoimprint materials, coating film thicknesses can be controlled to obtain locally optimized film thicknesses for the specific nanoimprint process. This process allows a more controlled way to optimize the residual layer thickness and total efficiency of the waveguide. Internal reflections within the AR waveguide are a major source for reduced contrast. The index matching light absorbing material provides a simple solution for controlling the internal reflections. When high refractive index substrate edges are coated with matching refractive index light absorbing coatings, there is a clear reduction in reflected and scattered light compared with non-RI matched solutions.

Enabling AR|XR Optics with Materials Innovation
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.

Large-area roll-to-plate nanoimprinting as solution for AR waveguide manufacturing
One of the primary cost-drivers of AR glasses is the optical waveguide. Yet, it is challenging to maintain the quality of the complex waveguide manufacturing in higher volumes. Large area Roll-to-Plate (R2P) nanoimprinting is a viable route forward, combining the UV imprint accuracies with the large-area display manufacturing method. Therefore, it is the proposed solution to manufacture optical waveguides for AR glasses in the consumer market.
At Morphotonics, we strive to build the foundation for a future where large-area R2P nanoimprinting produces AR optical waveguide combiners in typical high quantity display volumes. In this talk, we will address the upscaling process required for AR optics manufacturing via large-area nanoimprinting as well as the current status in terms of performance, materials, and manufacturability. Additionally, we will highlight the exemplary work recently undertaken with our industry partners to validate the entire value chain from design to mastering to replication on panel-level nanoimprint equipment using rectangular high refractive index glass substrates and high refractive index resins.ac

Metasurfaces: from lab to mass production
Metalenz is commercializing metasurfaces--a new optical element that allows complete control over all aspects of light (phase, wavelength, intensity, and polarization) with a single, planar semiconductor layer. Comprised of subwavelength nanostructures, a single metasurface can carry out optical functions typically requiring four or more conventional refractive and/or diffractive optics. In this talk, we will discuss how we’ve taken metasurfaces from lab to commercialization and how Metalenz’s ability to simplify and shrink complex optical systems enables advanced sensing for improved XR experiences.
