The market of augmented reality (AR) device has been growing and continue to speed up the process in these years. Among many different types of design, the diffractive waveguide type becomes one of the most important mainstreams in the market. In this webinar, we will introduce a workflow solution to design and optimize the waveguide, which is also called exit pupil expander. In this workflow, the initial 1D or 2D gratings are first designed and analyzed in Lumerical Design Environment. That gratings can be parameterized where the geometry is controlled by a few defined parameters. During the raytracing, OpticStudio automatically calls Lumerical RCWA in the background via an API for solving electric field for the gratings. The parameters in Lumerical are exposed in OpticStudio UI through this API. We will demonstrate how users can change the grating geometry from OpticStudio UI and trigger Lumerical to calculate new data automatically. A simple example of optimization is also demonstrated.
