This course will introduce the basics of designing diffractive waveguides for augmented-reality (AR) displays. Course topics will include an overview of widely used architectures for AR displays, an introduction to the performance metrics used to describe them, a review of the basic physics (such as the operation of diffraction gratings and photometric units) necessary to design AR waveguides, an introduction to the three basic steps in waveguide design, and examples of how to perform these steps to design both surface-relief-grating-based and volume-bragg-grating based waveguides. These steps will be demonstrated using VirtualLab, a commercially available optical design tool. This course will also discuss waveguide fabrication techniques and the test equipment used to measure waveguide performance.
