Ansys Lumerical FEEM

In this learning track, we will learn about the Ansys Lumerical FEEM solver and see how to set up, run, and analyze a simulation. We will first discuss the algorithm used in the Ansys Lumerical FEEM (finite element eigenmode) solver to find the eigenmodes of a given structure and the properties of those modes. We will also discuss the overlap and power coupling calculations, the feature to track modes as a function of frequency, and how properties such as dispersion and group velocity are calculated. Then, we will learn how to use the FEEM solver in the finite-element IDE to find the optical modes of a silicon waveguide and calculate the effective index and group index of a waveguide. We will learn about the workflow of the simulation, including how to set up, run, and analyze the results of the simulation. We will also discuss the main parts of the finite-element user interface. Finally, we will learn about various simulation objects used in the FEEM solver.

Lumerical FEEM — Simulation Objects

In this course, you will learn about various simulation objects used in Ansys Lumerical FEEM. By the end of this course, you will be able to understand common settings in the Mesh and Modal Analysis tabs and set up the (n,k) Material Attribute object. Other simulation objects such as boundary conditions are similar to other solvers in the finite-element IDE.
