The Perfectly Matched Layer (PML) is the gold standard for absorbing boundary conditions in FDTD simulations. PML boundaries are designed to absorb incident radiation with minimal reflection, effectively simulating electromagnetic wave propagation to infinity. The PML achieves this by implementing an impedance-matched absorbing layer at the simulation region edges.

In this tutorial, we have provided a comprehensive guide to Lumerical FDTD, covering the basics of the software, setting up simulations, and post-processing results. Lumerical FDTD is a powerful tool for simulating and analyzing the behavior of light in various photonic devices and structures. With its user-friendly interface and advanced features, Lumerical FDTD is an ideal choice for researchers and engineers working in the field of photonics and optics. The Perfectly Matched Layer (PML) is the gold

When you launch Lumerical FDTD, you are greeted by the main Graphical User Interface (GUI). The workflow always follows a strict four-step pipeline: Creating Geometries Locate the Structures dropdown menu in the top toolbar. This profile or linear monitor calculates the transmission

Even experienced users fall into these traps. This Lumerical FDTD tutorial would be incomplete without troubleshooting.

Silicon and Gold are dispersive (index changes with wavelength). Lumerical uses multi-coefficient models (MCM). Go to Materials → Edit → Ensure "Use fitted data" is checked for your wavelength range.
