Advancing the Human-Computer Interface Through The Development of Etched Silicon Carbide Waveguides

ABSTRACT: Augmented Reality (AR) is poised to revolutionize human-computer interaction by seamlessly integrating digital elements onto our physical world. To realize this vision, it is crucial to develop displays that blend effortlessly with reality, maintaining a compact form factor without obstructing the user with artifacts or perceptual mismatch. Although progress has been made, further breakthroughs in Optics, OptoElectronics, and Photonics are essential to meet the rigorous requirements of size, quality, efficiency, and cost. Silicon Carbide emerges as a lightweight, and durable material with a high refractive index, enabling a wide field of view with minimal rainbow artifacts.

This talk will explore these waveguide technologies as integral components in the journey towards a new era of human-computer interfaces.
