Move your PML boundaries further away from the waveguide core. Give evanescent fields room to decay naturally. If you need help setting up a specific device, let me know:
The official manual is dense with valuable information that is frequently referenced in advanced tutorials and support articles. For example: | | "Material data not found for wavelength" | §7
): For accurate results, your spatial grid step should ideally be smaller than inside the material. Step 2: Establishing Materials in the Material Registry Before drawing components, define what they are made of. Assign a fixed value (e.g., for Silicon, for Silica).
