Ansys Lumerical FDTD
The industry standard for simulating nanophotonic components, procedures, and materials is Ansys Lumerical FDTD (Finite-Difference Time-Domain).Â
Simulation of Nanophotonic Devices
Ansys Lumerical FDTD, employing the finite-difference time-domain method (also known as Yee’s Method), offers best-in-class solver performance across a wide range of applications.
The integrated design environment offers advanced post-processing, optimization, and scripting capabilities, allowing you to concentrate on your design while leaving the rest to the software.
Engineering Solutions
Photonic Inverse Design
- Automatically find the optimal geometries and designs for a specific design goal. Find counterintuitive geometries that enhance manufacturability, reduce area, and optimize performance.
Robust Post-Processing Analysis
- Far-field projection, band structure analysis, development of the bidirectional scattering distribution function (BSDF), Q-factor analysis, and charge production rate are only a few of the robust post-processing techniques available.
Anisotropy and Nonlinearity
- Simulate devices made from nonlinear or anisotropic materials that fluctuate spatially.  Select from a variety of gain, negative index, and nonlinear models. Leverage adaptable material plug-ins, and define new material models.
Multi-coefficient Models
- Deploy multi-coefficient models to accurately simulate materials over a wide range of wavelengths. Source  sample data (API configurability) to automatically develop models, or create your own procedures.
3D CAD Framework
- For both 2D and 3D models, FDTD’s CAD environment and parameterizable simulation components enable quick model iterations for engineers.
