Lumerical Fdtd - Tutorial 2021

The FDTD method is based on the following steps:

Next came boundary conditions. The tutorial had awoken her to the importance of perfectly matched layers and symmetry planes. She enabled mirror symmetry to halve the domain—there had been advice about speed versus artifact. This time, the symmetry nudged the simulation, and the resonance grew clearer, but its Q factor was lower than expected. Absorption at the edges? Numerical leakage? She adjusted the PMLs, extended them, tuned their decay. The peak grew narrower, as if the cavity itself were learning to hold light more tightly. The FDTD method is based on the following

Lumerical FDTD is a powerful software tool used for simulating and analyzing the behavior of light in various photonic devices and structures. The Finite-Difference Time-Domain (FDTD) method is a numerical technique used to solve Maxwell's equations in the time domain, allowing for the accurate modeling of complex optical systems. In this tutorial, we will provide a comprehensive guide to using Lumerical FDTD, covering the basics of the software, setting up simulations, and interpreting results. This time, the symmetry nudged the simulation, and
