Ansys Lumerical FDTD is a cutting-edge software tool that utilizes the finite-difference time-domain (FDTD) method, commonly known as Yee’s Method, to deliver outstanding solver performance in a wide range of applications. With its integrated design environment, this software offers advanced post-processing, optimization, and scripting features, enabling you to focus on your design work while letting the software take care of the rest.
How to raise fibre-to-waveguide coupling efficiency by co-designing a grating coupler and a microlens. Fields solved in Lumerical FDTD are passed to Zemax OpticStudio as ZBF, where POP is used to evaluate lens curvature and placement in a multi-scale analysis.
How to reproduce and verify the design and analysis of H1 and H2 photonic crystal nanocavities in Lumerical FDTD and MODE varFDTD, covering resonance spectra, symmetric boundary conditions, mode profiles, mesh settings and Q-factor evaluation.
A full three-dimensional model in Lumerical FDTD of a focused beam interacting with gold posts on a DVD disc surface. Near-field images and far-field radiation patterns are compared with and without the post, and a dimension sweep finds the smallest gold post that still gives a usable modulation signal.
The design flow for a diffractive metalens built from cylindrical nanorods, worked across Ansys Lumerical and Zemax OpticStudio: building a phase library from unit-cell analysis (FDTD and RCWA), full-lens analysis by field reconstruction, system-level evaluation with POP, and GDS export.
