Index Monitor in Ansys Lumerical FDTD — Lesson 2

Results & Applications

The index monitor records the spatial profile of refractive index or surface conductivity. In this video lesson, you will learn when and how to use it.

Setup & Tips

The demonstration in the following video shows the setup of a refractive index monitor in a simulation file containing a photonic crystal cavity structure composed of a slab with a pattern of holes etched in a hexagonal pattern around the center of the cavity.

If you want to follow along with this demonstration, please download the associated script file. Open the script file using the FDTD and run the script from the script file editor window. This will set up the objects in the simulation file so they match the starting point of the demonstration.
