: Best for testing flat interfaces, metasurfaces, or thin films.

For most nanophotonic applications, use a or a Total-Field Scattered-Field (TFSF) source. Define the wavelength range (e.g., 400nm to 700nm). lumerical fdtd tutorial

Design Note: Always ensure the source spans well beyond the edges of your waveguide to prevent diffraction artifacts at the injection plane. Step 4: Placing Monitors and Recording Data : Best for testing flat interfaces, metasurfaces, or

Check the to ensure the multi-coefficient model (MCM) fits the data accurately over your target wavelength range. Creating Geometry : Best for testing flat interfaces

When you open Lumerical FDTD, you are greeted by the main Layout Editor.

: Best for injecting light into guided structures like silicon waveguides or optical fibers.
