S-3: Waveguides for MR: Principles and Applications

Andreas Georgiou

Independent Consultant

Reality Optics, Ltd.

Future mixed-reality headsets will undoubtedly use waveguides to achieve a spectacle form factor and, if required, optical see-through. Mixed-reality waveguides were unheard of 10 years ago but are now receiving billions of dollars in investment. This course will present the operating principles for diffractive and reflective waveguides and give examples of their use in existing MR products. The gratings theory is described for diffractive waveguides, emphasizing the k-space representation. Different grating technologies are then presented, including Volume Bragg Gratings (VBGs), Surface Relief Gratings (SRGs), and Polarization Gratings. Reflective waveguides are also described, including their manufacturing methods, advantages over diffractive waveguides, and shortcomings. Finally, the operation of a few existing waveguide-based headsets is described. At the end of the course, the attendee will understand the primary function of the waveguide as a combiner and an exit pupil expander and learn the different approaches to creating one. 

Andreas Georgiou is an independent consultant with Reality Optics, Ltd., with a particular interest in computational problems in optics. He has worked in diffractive optics for over two decades and over a decade in mixed-reality optics. Georgiou enjoys innovating with head-mounted displays, three-dimensional displays, and sensors by combining physics, mathematics, engineering, and software. Before his current position, he has worked with many product groups at Microsoft (Surface, HoloLens, Azure, and Kinect), developed micro-confocal endoscopes for surgery, designed space instruments for Mars, and developed the first truly holographic display. He obtained his Ph.D. in optics from the University of Cambridge and is also an engineering research fellow at Robinson College, Cambridge. He has over 30 patents and over 20 peer-reviewed publications on head-mounted displays, data storage, holographic displays, and data transmission.
