Computational effort scales linearly with the number of simulation grid points ( 2. Navigating the Lumerical User Interface
Once you have a grasp of the basics, it is time to apply them to real-world problems. The is an essential next step, as it provides detailed descriptions of product features and an overview of simulations. You should then explore the Ansys Lumerical FDTD learning track , a free, comprehensive, self-paced learning track that covers the underlying solver physics, material models, sources, monitors, and post-processing. Supplement your learning with the "Introduction to Waveguide Design using FDTD" series, which introduces key concepts like mode sources, allowing selective excitation of specific waveguide modes, and explores how FDTD is used to study light propagation in photonic crystal waveguides and ring modulators. For a more structured academic approach, consider the tutorials from the University of Hanover, which demonstrate Lumerical applications in integrated optics, nanophotonics, and include post-processing integrations with MATLAB and Python. Best for structures near or smaller than the
By following this guide, you'll gain a solid understanding of Lumerical FDTD and be able to apply it to your research or work. Happy learning!
Lumerical FDTD solves Maxwell's curl equations on a discrete Yee grid. Time is stepped forward, and electric (E) and magnetic (H) fields are updated alternately. Key features of Lumerical’s implementation include:
