Ansys Lumerical FEEM

In this learning track, we will learn about Ansys Lumerical FEEM 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 Eigen-Mode) 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 Ansys Lumerical FEEM.

A track completion digital badge allows you to showcase your expertise and get recognized globally. We partner with the Credly Acclaim platform. Digital badges can be used in email signatures, digital resumes, social and professional media. The digital image contains verified metadata that describes your participation in the specific learning track consisting of multiple courses. This digital badge is for successfully completing the Ansys Lumerical FEEM track.
