The market of augmented reality (AR) devices has been continually growing in the past few years requiring innovative design types. Among the many different types of design, the diffractive waveguide type has become one of the most important mainstream designs in the market.

Join Ansys Applications Engineers, Michael Cheng and Kyle Johnson for an introduction to a workflow solution for design and optimization of the waveguide.

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.
