Lumerical FDTD tutorials are designed to guide users through the complete workflow of nanophotonic simulation, from initial setup to data analysis. Official documentation and comprehensive PDF guides often cover the following core areas: 1. FDTD Core Workflow
A standard simulation follows a specific sequence to ensure accurate results:
Define Materials: Use the Material Database to specify refractive indices and other physical properties.
Geometry Setup: Draw structures such as rectangles, circles, or waveguides.
Simulation Region: Set the simulation time, mesh refinement, and boundary conditions (e.g., Perfectly Matched Layers or PML to prevent reflections).
Sources & Monitors: Add optical sources (like plane waves or dipoles) and monitors to record data such as electric fields and transmission.
Run & Analyze: Execute the simulation and use visualizers or scripts to plot results like reflectance and absorption. 2. Key Learning Resources (PDF & Online) Reference Guide - ResearchGate
This is where FDTD differs from other solvers. The tutorial must explain how to define the simulation span and, more importantly, how to set boundary conditions (PML, Periodic, Bloch). It should also introduce mesh override regions—essential for ensuring the mesh is fine enough to capture small geometric features like a thin gold layer or a narrow gap.
