In this learning track, we will start with discussing the algorithm used to find the eigenmodes of a given structure and the properties of those modes in Ansys Lumerical FDE. We will then learn about the material database and how to add new materials, followed by a detailed discussion of the properties that are set in the Lumerical FDE solver. Next, we will learn about the workflow for setting up an FDE simulation to find the supported modes of a waveguide and analyze the frequency response of the modes. We will also learn what types of devices and applications can be simulated using the finite difference eigenmode (FDE) solver, as well as the types of results that can be obtained using the analysis tools. Finally, we will discuss how to run the Lumerical FDE solver, use the built-in analysis options, get results using the scripting language, and export results. We will also discuss convergence testing for verifying result accuracy.
