Lumerical Fdtd Tutorial Pdf Updated

Introduction

3. Step-by-Step Workflow (Conceptual Tutorial)

3.1. Project Setup

• Units: Set global units (e.g., µm, fs, THz) under “Simulation” → “Simulation Region.”
• Background index: Define the surrounding material (e.g., air ( n=1 )).

Future work could include:

• Create a new project and define simulation parameters (e.g., wavelength range, grid size, and material properties).
• Define the geometry of the structure to be simulated (e.g., a simple waveguide or a photonic crystal).

The tutorial will cover the following topics: lumerical fdtd tutorial pdf

Mesh Sensitivity: You must perform a "Mesh Convergence Study" to ensure your results don't change significantly when the mesh size is reduced. Introduction 3
