Hi, I'm Federico.
Hi, I’m Ahsan.
We are applications engineers at Lumerical. and we will be presenting this introductory
course on the Finite-Element EigenMode (or FEEM) solver, available in Lumerical's multi-physics
design software DEVICE.
The FEEM solver is used to calculate the characteristic modes or eigenmodes supported by waveguides,
fibers and transmission lines with uniform cross sections.
The built-in tools in allow you to view the electric and magnetic fields of each mode
over the cross section of the structure, and compute many common quantities used by designers
to characterize eigenmodes, such as effective index and propagation loss.
The FEEM solver can also be used in combination with other solvers in DEVICE for applications
that require multi-physics simulations, such as electro-optic or thermo-optic modulators.
We will start with a brief introduction to the FEEM solver physics and its capabilities,
followed by a demonstration of how to set up, run, and analyze results for a simple
This section of the course can be taken as a standalone tutorial for existing DEVICE
users, who are new to FEEM, to get up to speed quickly.
In the remainder of the course, we will cover other applications and more advanced features.
The course is intended for users already familiar with the basic simulation workflow in DEVICE,
which is described in more detail in other EDU courses, such as DGTD 100.
If you are new to DEVICE, don’t worry.
We have included several links throughout this FEEM course that will guide you to different
sections of these other EDU courses, so that you can get familiar with the design environment
and workflow in DEVICE.
Don’t forget, anyone who passes the FEEM 100 course will receive a Lumerical University
certificate of achievement.
