This video serves as an introduction to Lumerical's Finite-Difference Time-Domain (FDTD) tool, which is a powerful electromagnetic simulation utility tailored for optical device design and analysis. The video covers how FDTD can be utilized to study light propagation, scattering, and interactions in various waveguide types, such as slab waveguides, photonic crystal waveguides, and ring modulators. The unique mode source feature in Lumerical FDTD, which enables the selective excitation of specific waveguide modes, is highlighted. The session wraps up by showcasing the graphical user interface of the software, emphasizing its layout and functionality.
