In this course, we will discuss the algorithm used to find the eigenmodes of a given structure and the properties of those modes in Ansys Lumerical FDE. We will also explain the overlap and power coupling calculations, the feature that tracks modes as a function of frequency, and how properties such as dispersion and group velocity are calculated. By the end of this course, you will be able to describe the algorithm used by the FDE solver, know when the FDE method can be applied, understand the difference between the overlap and power coupling quantities, and know how the overlap frequency sweep calculations are performed.
